I'd certainly recommend investing in Eth especially with the late problems with bitcoin and especially it's transactions that are taking exorbitant amount of money as fees and a lot of time to confirm which can be frustrating for a lot of people , unlike Eth that has a much minimal fees and much more faster transactions . Ethereum is also much cheaper than bitcoin which makes you able to invest in more quantity and is having much more ground to expand unlike bitcoin which is facing a stagnation period at the moment .
