Yes i have mined bitcoin maybe around .3 bitcoin and i do have non mineable coins also such: cardano, vechain, tezos, xrp, some celo , pchain and stellar and i also forgot i have some sumcoin too.
You have experience mining a lot of coins, maybe you can assess by yourself which one is good for the long or short term, I mean which is your opinion gives a good return after deducting the fund for buy mining equipment and also electricity costs.
Several coins that you mentioned, in my opinion, only BTC and LTC are worth saving for the long term, the rest is only for the short term.
