A great one to invest in is #Blocnation. (not financial advice)
What I love about this project is that their product has a material state that you can actually "hold".  That is their bracelet having a NFC cip integrated.
This cip will be used to pay for whatever drink you want to whatever girl you wanna seduce at whatever concert you participate (that has partenered to #Blocnation). Use blockchain to pay for your wiskey or beer at Tomorrowland. Cheers mate!
Oh, yeah. Check out more details here: https://blocnation.io/
