The best thing I can say is to invest your 10 or 20% money into cryptocurrencies I mean not Bitcoin but other altcoins. Altcoins these days are suffering from huge price volatility so it makes a good time to make a profit. Just research multiple altcoins and make a top 10 list to invest in. I am sure top altcoins price will get restored into their original price when the bitcoin price starts rising.
I also make altcoins the main investment compared to bitcoin, this is because the potential increase in the price of altcoins is greater than bitcoin so we can get big profits.
