The set of companies & foundations centered around blockchain, cryptocurrency, distributed ledgers, and related technologies. Coinbase, Binance, CoinMarketCap are doing great, Bitmain would be doing great except they made a terrible bet on Bitcoin Cash, a number of other organizations (VeChain, IOTA, Ripple, Stellar, Ethereum) are doing "we'll see", and still others (Bitfinex, Tether, Bitcoin Cash, Bitcoin SV) are imploding dramatically.
The whole space is a pile of scams the entire way down. As we are just now learning, tether, the "stablecoin" that makes up the backbone of the entire crypto economy was basically a fraud.
The tech has had 10 years and so far it has produced absolutely nothing of value. In fact considering the damage it has done to the environment, it has been only contributing negative value to the planet.
