I play all of these except for the gambling ones. I save up the DEC from Splinterlands to buy new cards. I did invest some STEEM in dCity but now I only use SIM. Saving up my Starbits for a card pack too.
My liquid HIVE is reserved for investing in the new game eXode! Have you heard of it? Would you like my referral code? You'd get rewarded for using it!
