This is actually my strategy with all of the Crypto trading I do. I believe ETH will continue to trend upward, so I have been purchasing/selling Alts with the intention of having more ETH today than I did yesterday. If coin XYZ is worth .001 ETH today, I hope it increases to .002 ETH (while ETH too increases in value against USD). It is a nice USD multiplier.
