naaaaaa . bitcoin cant replace by any other cryptocurrency . if ever they can replace bitcoin , its ok bitcoin has done to it .
Maybe Yes, and maybe No too, because we cannot predict on how long the bitcoin will rise and low and we do not know if somebody will do another coin and hit the high price as bitcoin does but then I guess it would be hard to beat bitcoin now because it is so in good condition and being known world wide.
I really doubt that Bitcoin will be replaced by another cryptocurrency, but anything could happen. There is no way to predict what is going to happen and it would take a really long time for another coin to just get near the price Bitcoin is at now.
