There are theories floating out there that the crypto cycle is expanding as the market matures. The whales are doing a lot more to manipulate the market these days than they used to, as well, which always happens as a new technology becomes more established.
My strategy with crypto is the same that I used with tech stocks during the '90s - buy quality, dollar-cost-average, and don't panic sell. If you do your research up front so you are buying quality coins, you can ride out the roller coaster and exit with a nice profit. Buy the dips on the way up if you have the cash. Don't stress if you don't.
If volatility makes you panic, you should not be in a market as volatile as crypto. And, for the average investor, don't be an idiot and buy on margin or take out a second mortgage on your house to buy crypto. JMHO, of course.
