Iota is expensive hot shit. XRB is the real deal. Binance and Bittrex will list it soon. Did you know why polo and Bittrex have not added iota despite the market cap is super high and pumped up?
Because they are going to add Raiblocks soon. 1 XRB will rich 50 dollars per coin soon. Bitcoin lightning will become a failure and everyone will move to Raiblocks
most exchanger are not adding IOTA because they must adapt their system to work on that new protocol and system,
even bitfinex is helping other exchangers on how to manage it.
