Bitcoin will keep controlling the market anytime because bitcoin is the world's first cryptocurrency so I think the bitcoin will never be replaced with safe alcoin so I'm a bitcoin picry that will keep controlling the market until whenever and in all these worlds but you might be able to replace bitcoin because bitcoin has been through how many seasons from 2009 until sakrang and there is also possibility bitcoin will die because bitcoin has survived from 2009 until now maybe bitcoin will also die in time how many years
I cannot see any compition of bitcoin with any other crypto currency, i think that bitcoin is the best crypto currency and therefore it is going to hold the market and the interest of the people for long time. Bitcoin is in fact the first crypto currency of the world and therefore people are taking more interest in bitcoin as compare to any other crypto currency.
