Impossible bitcoin could be over because many investor keep trust with bitcoin, keep holding and waiting with bitcoin growing up to higher price, maybe bitcoin could be over when all country have banned bitcoin.
Bitcoin's price now is 3500, I dont think it grow up, perhaps it would fall down to 3000. Should I invest in?
There are too many blockchain projects to simply ban most of the cryptos. Especially the one which psychologically is regarded as THE cryptocurrency. And halving of BTC reward in 2020 will give a major boost to its price. Remember that with a reputation of virtual gold, BTC will be always subject to speculations, just as precious metals. Yet of course, someday Bitcoin will lose its importance and possibly its reputation will fade away. But it is not going to happen anytime soon.
