I would say that you can't go far wrong investing in any of the top market cap coins right now, as they have all fallen in value and can be bought at bargain basement prices. ETH has fallen significantly and is currently at a very attractive price.
If I was to mention just one, it would be Oyster (PRL) as I can really see it taking off once they launch their tech, and on April 6th they are taking a snapshot and airdropping their secondary coin (SHL) on a 1/1 basis, so for each PRL you hold in your wallet you will get one SHL. The price has already inflated a bit though in anticipation.
It is all speculation though, you have to do your homework before investing in anything and be prepared for the worst, as the market is still not in great shape at the moment.
I agree. Ethereum is beginning to gain its value back once again, so before it achieves it's max price point, it's better to invest in it now, especially since the coin is going up. It's a good time to invest because you won't have to wait for a long time to get a profit as compared to buying coins when it's at its lowest point because although you would surely have profit, you would have to wait for a long time before that profit can be realized.
