OUR ATTITUDE TO THE CHANGE OF BITCOIN PROTOCOL
Created 19.07.2017 12:07 Due to expected changes in Bitcoin protocol and possible splitting of the chain to 2-4 forks of Bitcoin, we want to make it clear for our clients.In the end of July some events will take place, which can potentially lead to dividing block chain into 2 or more forks, you can read about this event in details following this link.

We follow only to an official recommendation from the bitcoin.org website. We use only bitcoin-core official node. In the case of fork, we will accept the chain which will be accepted by an official bitcoin-core client. 

However, by the end of the July, we're planning to close BTC deposit/withdrawal till the full resolution of this issue according to an official recommendation. If a split of the chain will take place (it might happen in the beginning of August) we will do all the possible to credit our clients with new Bitcoin forks as well as to save an original BTC balance. We will allow trading of new forks if they come to live. Closing of deposit/withdrawal is a necessary measure which is required to credit your account with Bitcoin forks. 

We increased temporarily an amount of confirmations required for incoming BTC transactions up to the 5. We will decrease this number to 3 when the situation is resolved.
