I just looked up Flappycoin! (along with Coinye)
Back in the day I would actually make decent money renting rigs and mining coins like Flappy for awhile. After doge profits fell a couple such as Flappy and MIM actually brought in quite a bit. Of course you had to sell to make any money. They are hanging out in a crypto coin graveyard now.
Yeah I mean it was a dumb investment unless you day traded the hype. Just thought it was a funny memory because I remember people buying coins for over the market value since they didnt know how to use exchanges.
