Hi, I am holding many Feathercoin (FTC) created in April 2013. Started in 2017 and accumulating since then.
If you look at the Hashrate, you can see that Feathercoin for more than 2 years has a hashrate average of 6 Ghz. This power is equivalent to 6,000 high-end GPU. In other words it means that Feathercoin is currently mined by a big actor.
We don't exactly who is behind but we know that something big is happening.
