Thanks for your comment, I'm glad that it was insightful.
I think that stop-loss and stop-limit, when used correctly, can, in fact, save a lot of money when let you leave in the first wave ensuring most of your profit. You need to know what you're doing or this tool can be even more dangerous than hold.
Absolutely true, buy and hold would be my suggestion for non-traders anyway but that's just me.
Thing is Coinbase is just a sketchy disaster, no customer support, throttling users when price is down so they can't buy and generally just unstable as hell.
Someone once said buying gold is flying in a 747 and buying silver is flying in an F-16 - same speed but vastly different flight experience. Cryptos is about 10 times worse than an F-16 in terms of volatility. If you know that and act accordingly you're good.
