Which are the best competitors to Ethereum, and why do you think so?
(I know on top of my head that Cardano and IOTA try to challenge Ethereum,
although they still haven't proved much from my understanding?)
Obviously I would say bitcoin, because for me crypto is only for 2 coins, in the end when you invest in an ICO or want to make money, the choice will only be in both, buying bitcoin or ethereum is a smart, safe and most profitable investment today .
