Volatility is part of what defines Bitcoin and some other cryptocurrencies. As the industry matures, the rise of cryptocurrencies that tracks the performance of less volatile traditional assets like real estates and commodities will likely bring a lot of beauty to the cryptocurrency industry. I believe that a mix of more volatile crypto assets and less volatile assets will give traders a lot of options to enjoy while trading.
Yes volatility of the crypto space is something that will likely remain with us however we can only but find ways to limit and play around it. Even most projects which claims to offer less volatile assets ends up getting hit with reality that most of them died off if not all. Also, about non volatile or less volatile assets, they are there to help both traders and otherwise to put a limit on volatility which is the reason stablecoins like USDT keeps growing in their number of users. Therefore I think it's better to invest in good coins which regardless of volatility will still offer something massive in the near future.
