Bitcoin and altcoins are growing in price at the same time, as we see, and many investors who bought bitcoin last year for 5k$ and Ethereum for 70-80$ can already sell their cryptocurrencies and get excellent profit, but I think that the growth will continue and we still need to wait.
Those major coins have big community and long term roadmap. There will be more and more innovations will be bringing out by them for us. We just waiting for that to happen in the future. Everything needs a process and it can't be done just in a night, a week or even a month.
Crypto has a very big vision for long term development.
