How come that it took me 8 years since the beginning to discover bitcoin/altcoins?
i did research for almost 2 years to find something like that and it never happened. and i did alot of research.
how is this even possible?
or do you guys know anything else like coins to earn some extra money?
Yes you can definitely earn extra money not only through btc or altcoins, there's a lot of airdrop and bounty program that offers free tokens, that soon can be cash out in an instant. You can check it on twitter and here in bitcointalk forum, so much information that we can gather in here.
