Pegascoin network was is in under attack 51 - double spending.
In this case  stoped all deposit and withdraw in all exchanges.
Hacker account on btc-alpha was locked, but he managed to sell coins and withdraw btc.
I will send requests to the exchange, to increase the time of confirmation of blocks for deposits up to 500-1000

Unfortunately, no network is insured against double spending, which is based on ETH.
Protection from double spending only a very high hashrate of the network .. and even that Nicehash can overcome this, as was the case with ETC
P2P exchange will be stopped to prevent its use by hackers.

------------------------------------------------------------------

Request to open deposit/withdraw sended to stex.
Deposit confirmation will be increased to 1000 blocks.
BTC-Alpha deposit will be closed for a while.
And do not create tiket to stex support with request: why deposit time is so long..
It is a necessity for at least some kind of protection against hackers..
