We are happy to announce new trading pairs LTC/EUR and LTC/CZK to be introduced this week. The deployment will require about a 10 minute system downtime on Thursday 24th May 10pm CET. We apologize in advance for any inconvenience the unavailability may cause you.
High and low priority Bitcoin withdrawal
We have become one of the first crypto exchanges to deploy dynamic bitcoin withdrawal fees, giving you the option to choose between a fast and economical bitcoin fee.
Bitcoin fees are now updated several times a day based on the bitcoin network situation. High priority withdrawals are processed within a few minutes and confirmed as soon as possible. Economical withdrawals are processed in hourly batches and targeted to be confirmed within 3 blocks. You can also choose between the 2 bitcoin withdrawal types when using our API.
We are expanding our team with additional developers as we plan to onboard new cryptocurrencies (Dash, Ethereum and Ripple). We are also very close to introducing a new competitive trading fee model. Stay tuned.
Dear coinmate users,
Please be informed that during Christmas Holidays (23rd December until 2nd January) our Customer Support will be very limited.
Please do not contact our Support or write emails during these days unless it is absolutely necessary. Response to issues may take up to 7 days and General support enquiries will be ignored. Video verification will remain active in a limited mode but reviewal of bank account statements and questionnaires will be postponed until 2nd January.
Deposits, withdrawals and trading
Single Deposits that do not fit your current 24-hour account limit will remain pending until 2nd January. Bank Deposits within your current account limits will be processed automatically and Bank Withdrawals within your current account limits will be processed on business days. Also, please be noted that it is possible to Deposit and Withdraw ONLY USING YOUR VERIFIED BANK ACCOUNTS. Faulty deposits (i.e. from accounts of other persons or cash deposits) will be returned after 2nd January and will be subject to a 10 EUR processing fee. Issue with Bitcoin processing has been fixed and Bitcoin Deposits and Withdrawals are now are being processed flawlessly. All trading will remain active and uninterrupted during the Holidays.
We apologize for such short notice but the enormous growth in new registrations, associated administration, overloaded bitcoin network with rising unconfirmed bitcoin transactions and bitcoin network fees in the past 30 days has been overwhelming on our staff. Thank you for understanding.
We wish you Merry Christmas and a Happy New year.
Dear conmate users,
be informed there will be a planned maintenance tonight 11th December starting 10pm CET, during which the website will be offline. Planned downtime is approx. 30min.
We are introducing Segwit addresses and changes to bitcoin processing as a first step in our efforts to decrease the bitcoin transaction fees. After the deployment tonight, the “Generate new address” button in the Bitcoin Deposit form will provide a new bitcoin deposit address starting with 3 (opposed to the old address format starting with 1). We recommend all users to begin using this new bitcoin deposit address type for bitcoin deposits as soon as possible. The old bitcoin deposit addresses will remain valid for another week, after which they will be deactivated. The automated trading API call “bitcoinDepositAddresses” will require generating the new address in the 1-week transition period.
Bitcoin transactions using the new Segwit 3-type addresses take less space in bitcoin blocks and thus contribute to efficiency and lower transaction fees. We are also switching to a more efficient bitcoin transaction processing model. In our further efforts to decrease the bitcoin transaction fees we plan to introduce a low-priority bitcoin withdrawal fee in addition to the high-priority fee (planned for January).
New trading pair Bitcoin Cash / Bitcoin will be added. Bitcoin Cash is a hard fork of Bitcoin, the fork occurred on 1st August 2017. Users that held any bitcoin balance in their CoinMate account on 1st August 2017, will be credited the same amount of Bitcoin Cash tonight.
Bug fixes, small changes and system optimization. There are several bug fixes and some small changes in this version including system and database optimizations to cater for increased traffic.
Thank you for choosing CoinMate.io
Dear Clients, we will be upgrading our portal to higher database instances. Our website wil undergo maintenance service on 15.11.2017 (22:00 – 23:00 CET).
We sincere apologize for any inconvenience this may cause you.
Your coinmate.io team.
We are currently 14.11.2017 9:00 CET, experiencing technical difficulties on our backend and are working to resolve the issue.
We will endeavour to restore operations as soon as possible.
on or about 16th of November 2017, approximately 90 days after segwit activation, bitcoin network will split into 2 independent branches: Bitcoin Core and Bitcoin Segwit2x (this will happen when block 494784 is mined). Segwit2x aims at increasing the current 1MB bitcoin block size to 2MB. Bitcoin Core will keep 1MB blocks.
Here is a brief summary of the history leading to this occasion.
Satoshi Nakamoto released first bitcoin software in 2009 and there was no block size limit for Bitcoin, except that implied by the 32MB message size limit. Later at the end of 2010, Satoshi decided to change the limit to 1MB, which was plenty enough at that time. The reason for such constraint was fear of network congestion that could be caused by spam attacks (it was possible to broadcast transactions containing no fee).
Since then bitcoin increased in popularity and transaction limits started to hit the constraint set back in 2010. Majority of the bitcoin infrastructure today relies on the referential software client Bitcoin Core (currently representing about 64% of all bitcoin nodes). And a part of the bitcoin community is raising concerns that there is no immediate solution to the now constant congestion of the bitcoin network.
So what is next?
Even though the bitcoin network operates at 100% of its capacity since January 2017, the Core developers are not in favor of the block size increase claiming that Bitcoin’s consensus rules should only be changed sparingly and with broad agreement from the entire community.
This opinion is at odds with the Segwit2x initiative. On 25th May 2017 58 companies from 22 countries, (representing 83,28% of hashing power) agreed to upgrade the bitcoin protocol to so called Segwit2x, which in effect should increase the block size to 2MB causing a so called hard-fork.
We at CoinMate will approach this situation responsibly and we will offer our clients the opportunity of choice. On the day of the split we will make a bitcoin balance snapshot and we will credit all clients owning bitcoin the same balance also in the other network. There is no action necessary on your side. Your bitcoins will be safely stored and access to bitcoin balance on both networks will be granted after the split as soon as it is safe.
Our planned procedure will be as follows:
- All bitcoin deposits and withdrawals will be disabled 24hrs prior to the split
- All trading will be intercepted approx. 1 hour prior to the split
- Individual bitcoin account balances snapshot will be made
- Trading will be restarted, the legacy chain will remain to be called BTC, the new chain B2X
- You will be credited B2X balance and deposits and withdrawals will be enabled once it is safe to do so.
Dear CoinMate Users,
we are glad to announce a new release of the CoinMate exchange portal. In order to perform the update, CoinMate.io service will undergo planned maintenance on Tuesday 19th September from 10pm to 11:55pm CET.
Bank withdrawal processing
In response to the increased demand for faster bank withdrawals, we are rolling out withdrawal templates and automated processing. Starting 20th September 2017 we will be processing bank withdrawals twice a day. First batch of payments will be processed at or about 11am and the second batch at the end of the business hours.
Improved Trade screen
Market stats and user trade history will be added to the Trade screen, everything elegantly packed for even better trading experience.
Security enhancement and API add-on
An extra security feature will be added to the password recovery process. And our API will be expanded with a new Order history call.
After improving our database and server infrastructure in the previous months, it is now time to introduce new trading pairs (Litecoin will be introduced in late October). We are also happy to announce that more trading pairs will follow shortly after Litecoin deployment.
We are resuming deposits and withdrawals after the Bitcoin hard fork. Bitcoin network appears fast and smooth. We made snapshots, backups and audit of all bitcoin balances on our hot and cold wallets in case we eventually add BCH into our trading platform in the future.
Your Coinmate Team.
Our position on bitcoin hard fork
It is very likely that on 1 August 2017 around 2:20 CET, the bitcoin network will be divided into two separate currencies. CoinMate will continue to support the current bitcoin, the bitcoin with the highest overall support across the community. Any second, “hardforked” branch i.e. so called Bitcoincash will not be supported at this time.
If you also want to deal with bitcoins in the other, “hardforked” network, you will need to withdraw bitcoins from our exchange into a bitcoin wallet that will allow you to transact bitcoins on both networks, or into a wallet that you hold private keys to. In such case make the withdrawal as soon as possible so that the payment can be confirmed in the new wallet no later than 1 August 2017.
At the same time, the BIP91 proposal has been activated. Under this agreement miners now reject blocks that do not signal Segwit. Due to the precautionary principle and the protection of our users, we will require 6 bitcoin confirmations for bitcoin deposits starting 28 July, 2017.
To ensure safety of bitcoin balance in your CoinMate account, we will disable bitcoin deposits and bitcoin withdrawals starting 1 August 2017 10am CET. We plan to resume bitcoin deposits and bitcoin withdrawals in the morning of 2 August 2017, if it is safe to do so. Trading will not be affected and will remain active throughout the whole time.
Dear Coinmate users, we will be performing server upgrades with high performance hardware today from 20:00 to 21:30 CET. Server upgrade was necessary to reduce recent timeout API problems. It will also speed up the response on our website.
