I would sell all my Bitcoins if bitcoin price going down and down..really down,and bitcoin expert predict bitcoin will not up again,its time i will sell all my bitcoin,i'm sure with that. however,real money is more accepted in my country,it time i will more relistic that money is better than bitcoin.
That day would never come
and bitcoins is no concerned with experts, experts predictions are always wrong, bitcoin itself is an revolution and it doesn't need any expert advice, if it gets support from the people it will keep on growing and one or two experts cannot change the future of bitcoins, if acceptance is higher, nobody can stop bitcoins in becoming a global currency.
