I've attended Faircoin airdrop long time ago. Kept the coins forgotten in the wallet, it is now aroud 3~4 BTC.
Woah - that's impressive!
I kept the coins for about 3 years, and still keeping. I'll be rich or get nothing....
If you kept your original Faircoin airdrop 3 years ago and did not follow the development, those coins will be worthless today. FYI there was a coin swapped that happened before as far as I can remember.
