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?)
bitcoin i think and maybe noe or eos something like this and you need to understajd taht it is ok not fo invest in the famous ones
I think EOS and NEO are the best competitors, because they are also smart contract. NEO supports many languages, and EOS lets community to vote for the changes in the code so it's very attractive in the long run.
continued progress shown Bitcoin Cash was able to invite BCH became the coin is so inflated and have more fans. increasing State-owned competitors, making it the best Cash Bitcoin Ethereum. This will be very good for the future of the Bitcoin Cash became the mainstay of the coin.
