I see that IOTA has a lot more advantages than disadvantages. Lets compare against the BTC Bitcoin will never be adopted as a payment method on a shop or store, first the speed on transactions are unacceptable, second on micro payments the fees are in many cases higher than the cost of what we are buying,

Comparing against Ethereum the Big issue with this " Crypto " is that it should not even be classified as currency.

As far as I know there is not limitation on the number of ether that can be mined, for this reason it becomes worthless.
