Since, you sound like a newbie in trading world, I would recommend you to divide your investment in 3 parts, put one in ETH, one in a coin of your choice, you can take a risk in this by going with some ICO or altcoin based upon their project idea and the last one in BTC. But don't invest in BTC at this point. BTC is pumped almost 30% in past few days which isn't a good sign and can undergo a dump if ETF doesn't get approved. So, wait for a while before investing in BTC. But go ahead with investing in altcoins where almost all are at bottom.
