I agree that Bitcoin is extremely risky, but I've looked at IOTA, and it's an utter nonsense project. It's centralized, because the tangle security model it purports to use doesn't work, and its developers have pulled antics like explaining away a flaw in the client code by claiming it was put there intentionally to thwart copycats, and claiming a "partnership" with a company after IOTA used that company's software. Hyperledger meanwhile is not a distributed cryptocurrency project. It's software for building consortium blockchains, meaning blockchains run by trusted third parties. I agree with you on Ethereum. It's now processing more transactions than all other decentralized blockchains combined, including Bitcoin.
