Well, I don't know about juld but I know about dego, am currently holding some dego NFTs which I bought some time ago, and to be sincere, I regret buying them cus am unable to sell it now or even withdraw it from dego mining as they are currently useless.
Holding dego token I believe is very OK, and this is the mistake I made, instead of spending so much money buying the dego Ethereum NFTs which are currently useless, I would have bought dego tok3ns which I believe will be very profitable in the future, I personally think dego token will be worth more than $10 usd in the future, so it's definitely good to hold.
