It would be awesome if one could earn so much by simply playing games. I really hope its true, because most of the blockchain games I know people play online have an element of cost and to earn, one needs to be financially committed. I understand that things are changing and some projects may introduce free games where one could earn.
With Lympo App you can earn $LYM-tokens for free just by doing Sport/daily tasks & challenges:

-> it's working but LYM-price is quite low at the moment, so you won't get rich here now. But if you're doing sports anyway it's a fun extra benefit..
