Everybody has he's or her own. the main issue of cryptocurrenqcies these days can be either stable for a long period of time, or they can stay highly volatile for a long period of time. Nowadays, cryptos are more stable than stocks, but I don't think it will be a very long-lasting trend, because all traders are familiar with cryptos. this comparison can be determined only by a thorough technical analysis or a fundamental one if we talk about long-term intentions.
I don't know where your reference of all traders being familiar with Crypto is coming from but in as much as crypto currencies is widely spreading and being adopted globally to the extend that even the stock traders are convenient in adopting the Crypto technology not just to stock their savings but also as medium of accepting payments from their customers and vendors, that's of course obvious that crypto had and would keep up topping the stock market.
Behold, bitcoin is fully represented with its solid volatilities with the potentials to uphold stable values for the cryptocurrencies.
