Newbie here and I want to start trading soon. Just want to get tips on when to invest on btc and eth. thanks in advance! 
Now is the right time for you to invest ETH.For BTC investment I think too late. See the current BTC price is very expensive.
But if you want to try it, I suggest to invest 30% -50% considering the BTC is needed.
Possibly in a few more years, the price will rise several times the current price.
