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
I suggest reversing the situation. the point is, you need to own 35% of each bitcoin and ethereum. after that, you can save the rest in an altcoin. In addition, although the potential for altcoin is quite large, the risks are also great. I assume that currently holding bitcoin and ethereum is the best decision.
