Whelp, you're not wrong, but you're not right either. There are more crypto currencies that have crashed and burned than those that haven't. NFTs are the short game of most of the grifters in crypto... Build hype towards a release, or "drop", prices go high after the IPO, then sink to nothing. Again, and again. It's entirely a confidence game for any new crypto at this point, and confidence drops off very quickly.

Aside from a handful or two of "currencies", the story is the same, over and over again.

Bitcoin is the best case scenario, and even that's unstable at best and downright chaos at worst; bluntly, the only reason IMO, why Bitcoin (and limited others) haven't gone under is because of the long term holders of the currency. There's large amounts of those cryptos that are being held, possibly forever, and sometimes, entirely lost on thrown out hard drives in landfills. The blind confidence that long term holders of crypto have, is keeping that hype train rolling. As long as nobody cashes out, nobody's as millionaire and it's just a matter of time.

Crypto was a good idea that attracted way too many grifters and confidence game conmen.
