I agree with you, if you invest in cryptocurrencies now, then in 5 years you will increase your savings several times. But as for the growth of the market, I recently think that this year there will be a slight increase. Good growth will happen next year.
You don't even have to wait 5 years if you just want to benefit from crypto because crypto is so flexible that only a few months can experience a high increase but sometimes people keep it and eventually come back down but will definitely rise again. I also believe that the market will soon rise. especially if there is a lot of positive news about crypto, crypto will rise faster.
