I'm gonna have to correct you there, BTC will stay on top for sure, other coins have risen but it is still not enough, BTC will be on top for a long time, but BTC is not invincible so I won't declare it as something that cannot be touched, however, some cryptocurrencies does not yet have the manpower to overthrow BTC because it is just really too big and people know that Bitcoin is the first thing you'll hear when you hear the word "cryptocurrency", don't claim it dead because BTC is still young and evolving, it doesn't mean that the price is being dumped doesn't mean it won't make a comeback.
