My current portfolio consists of 25% BTC, 25% ETH and the other 50% pretty much equally divided between EOS,BNB,TRX,NEO,BAT,XTC,ETC,WRX and ADA.
BTC and ETH are both relatively safe investments but I personally think the ALTS I hold will potentially yield far greater profits
Of course, altoes will bring more profit, but it is more risky to invest in them. Also, alts will start with a rise in the price of Bitcoin, so it is worth investing in both Bitcoin and some alts.
