Well, I am very happy to use bitcoin, and even I have been accustomed to look for bitcoin every day. if suddenly the government says it's illegal, it is a difficult thing for me. however, for a more secure, maybe I'll start to move away from the bitcoin and try to use altcoin which has the same potential as bitcoin, but I guess it takes a long time to get away from the bitcoin.
If something like that happened maybe a crash on the price of bitcoin will follow, so maybe we will not have too much of a choice and will need to leave the crypto currencies market or move to another coin with the risk the governments make that coin illegal as well..
i don't think so , even there is ban regulated by government ,
it will not provide a big effect to bitcoin price in long term ,
also people will remain use bitcoin no matter what ,
so do i , but i doubt there will be a lot of government can do recognize bitcoin as illegal thing.
