no problem was originally so, I see this project is similar like XRB aka nano, free distribution initially until last year of October, but see now.
around 8% of tokens where distributed during airdrop (whole market) I don't see any relation with this but probably the big hype of the price was corrected with new values. in just a couple of weeks we have seen a +500%! the price can't grow forever, and it's normal to see this downtrend.
