You should check out GET. If they are lucky, they might become a (small) competitor of Ticketmaster in the future.
Chances are small but I believe that they will atleast grow once events can go back on sale.
Sorry but in my opinions now nft token are overvalued. I know also that can still grow...but the (now) risk is high
NFT are still on its up trend since the hype is still here so it can still be a good time to invest and play short.
Anyway, based on the OP list I can say that you are already holding a good projects but if you are still looking for altcoins to invest for then I can suggest that you make your own analysis about Poolz and DIA because for me they are also good for long term holding.
