I've invested in TIME cause it has the highest APY currently.

As for buying it, I don't think it is as hard as you're making it seem. You really just have to buy the coin on the right chain and stake it on the app.

With TIME, when you stake it you get MEMO. You can then Wrap your MEMO (to wMEMO) and stake it on the Fantom chain for an additional 160% APY.
