Personally i`d invest in MWAT, they already have a product in the energetic field and already started the expansion, with more to come of course. If i`m not mistaken you can do some research yourself and check if you can open a franchise yourself (=passive income aswell). Also you can get more tokens from downloading the app they just released and also from refering your friends to do so. Or you can just go for ethereum, that buys you 2. something ETH but with this market idk if its gonna go that high up so you`d have a profit anytime soon.
