Bitcoin core will disappear in 1-2 months. What will happen with your coins? They will have
NO value. The miners and exchangers will make the change overnight.

The big miners along with few exchangers (Bitstamp, Coinbase, BTC China, OKcoin = same shit) will switch it to Bitcoin Classic.
BitFury CIO Alex Petrov
""If the Bitcoin Core team doesnt deliver [a solution] in time, we should force the process and thats why were supporting classic. Its not the best way, its painful, but we should do it.""
"It will be not easy to implement, but we can do it one month. This is why we are supporting Bitcoin Classic."
