I'm compiling a list of 50 crypto to HODL in 2018 together with 22 other crypto ethusiasts. None of your 3 are on the list. EOS is more usable than ADA at the moment, but ADA is an order of magnitude more advanced and the right direction for serious adoption. If I wanted EOS I'd just use Ethereum.

Bitcoin is a dying horse, unless you mean Bitcoin Cash.

IOTA? Don't understand the hype really.
