Anything that holds or has value, is valuable.
Tickle-Me-Elmo dolls, had you been able to buy a truck load or 2 of them, could have made you rich as you could have sold or traded them for anything you wanted several years ago. They did not retain their value, though. Gold and silver have.
Crypto is different. Right now it is more of an expectation to have and hold value, in the future. A speculative store of value (other than the ones that are already being used like BTC, LTC, ETH, etc.)
So yes, crypto is valueable. Anyone that says otherwise is kidding themselves, and probably anti-crypto.
