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.
