Bitcoin is the oldest and most valuable cryptocurrency, but a crop of nimble competitors, including Ethereum and Bitcoin Cash, could lure investors away.
If you think of the current coinmarketcap Bitcoin is weak, I think it would be wrong. Because the way the storm has increased in the past, our hope will increase again just like that. So compare to other coine with Bitcoin can not be given. Bitcoin is called because of the coinmarketcap boss. And it's like an earthquake, so bitcoin can roar suddenly.So it can not be trusted without it. Because we do not know what will happen in the future.
