Anything that uses blockchain is crypto. So bitcoin is crypto!
That's so untrue! IOTA doesn't have a blockchain... All transactions are recorded on a private ledger. The point wasn't even based off of the fact that cryptocurrencies don't have blockchain so what are you saying?
Excuse me, I was wrong. I don't really mess around with alts much, but you're right. I think IOTA uses something called Tangle (correct me if I'm wrong), and it doesn't solve blocks or something like that? To be fair, its functionality is very similar to blockchain.
