For trading on IDEX, I will give you some ideas of mine:
BPT - Blockport, marketcap $5.2M
ELIX - Elixir, marketcap $2.7M
CARD - Cardstack, marketcap ??
or if you want a well established project then
IOST - The Internet of Services, marketcap $145M
I think out of the 3 , the best will be BPT is a great project and has been holding pretty good in these bear market , when the bulls arrive wich I think it will be pretty soon these one will skyrocket!
