Now the eth price very low compare to this year January. ETH price went up to 1500$ but now around 200$. I think eth price will rise again at least 1000$ near future. So, holding eth also a good at this market condition. If you want to multiply your eth amount you can invest coins like ADA,TRX, EOS etc which in top 20 in cmc.
Cardano last month, lost two of the largest investors, and have problems within the team.
EOS also have a lot of complaints, many users do not even call it a blockchain.
But TRX shows itself pretty well. Fast network, cheap transactions, make it a promising investment.
