I don't think any other cryptocurrencies value could really catch up bitcoin price. The train already passed. But there still a lot of opportunities for other crpytocurrencies, since blockchain technology is so useful in many ways. And now the stock market and real estate market is already quite high, a lot of money would come to cryptocurrencies, there are a lot of coins are in the low price.
Bullshit. Bitcoin's price is only so high because of speculation, ethereum however has real support and has already a 63b market cap compared to 300 of bitcoin, is not far from reaching it. Bitcoin will eventually ''crash'' not to 1k dollars but still it's going to happen eventually.
