The "volatility" meme that the paypal CFO refers to is silly. Buy low, Sell high; it's that simple, you don't lose money unless you sell below your buy point, so don't do that. Living in fear is not the way, stay away from crappy coins with low volume. I stay within top 20-50 and have made solid gains over 6 month periods. If that's too long then, well, go make money elsewhere. Learning how to profit from crypto isn't difficult.
