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 think you should invest everything which is surplus with you in bitcoins. Many people invest in Gold and property, but the ROI in them is very less. If we invest in Bitcoins, it will surely be 2x in matter of one year or so.
