I like both, DOT is also increasing in price and have been showing an interesting chart for a few days now and ETH hitting that new ATH definitely did us a favor. But choosing between them is impossible for me, I believe they're both showing their best right now, when isn't even altseason yet, gotta watch them play the game well.
