if you wanna start here is my cheeky ad link:
https://sorare.com/r/once ( we both get 1 limited card if you buy 5 cards off an auction )
its like a fantasy football but with crypto cards ( NFT ) with dozens of different leagues and competitions. there is a free 2 play league with common cards only aswell ( you get like 10-12 common cards at the start )
you would need to spend like 500€+ to get a decent rare team that plays every week but the ROI is pretty decent if you get to the ETH threshholds for certain points
im trying to trade myself up from a really small budget but its decently working right now
