As long as IOTA fail to become decentralized I refuse to call it a cryptocurrency. And if I had to chose I'd rather invest in NANO than IOTA.
Would you like to call the decentralized cryptocurrency as a fail crypto too since it was fully centralized like IOTA and NANO? I think that you would not call that as a failed crypto lol
That's the problem but i never heard the centralized has brought IOTA DAG into the serious problem like the double spend or something else.
