IMO crypto is a scam and a vehicle for money laundering. National currencies are not perfect by any means but as mentioned earlier do relate back to the real economy, Whereas crypto has no intrinsic value whatsoever. Where the money goes to after the purchase of crypto is anyone's guess but one thing you can be sure of is it is not held in reserve in case of a run on the particular crypto. Crypto has all the hallmarks of a Ponzi scheme and would collapse tomorrow is there were a serious run on it.
