I wouldn't advise investing in crypto as a saving money strategy, it is still a very high risk investment. As the OP mentioned, the top ten are in a lower risk category, but still high compared to investing in something like property or bonds. I'm investing in crypto for bigger gains down the line, but understand the risks associated with that. If I lose everything I've invested, I can still fall back on other income. This is fun for me, I like risk, but only with money I can afford to lose (and maybe a little bit more).
