Criticised IOTA back in 2018 for the same things IOTA later on got troubles with in early 2020;

"“Today,” Brekken began back in early February of 2018, “I’m reviewing IOTA, a token that uses a tangle instead of a blockchain. IOTA is supposed to be used on small devices in the Internet of Things. I’ll show you how to buy, store, send, and sell. TL;DR: IOTA cannot be used for Internet-of-Things devices. Or anything.

“IOTA is the worst cryptocurrency I’ve reviewed so far,” Brekken finally insists. “Installing the IOTA wallet was a pain. Receiving and sending IOTA tokens is technically challenging and time consuming. Address reuse can lead to loss of funds.” Beyond loss of funds, he also cuts at the heart of its value proposition, noting it cannot even be used for the “internet of things.” In classic Brekkenian philosophy, he cheers, “IOTA is a shitcoin. I don’t recommend buying or holding it. I’m even going to short it. However, if you choose to go against my recommendation, trade on Binance with my referral link. At least then your misery helps me.”"
