Maybe FLY team should hire this guy or another competent dev to code their coin. It is basically unusable since all exchange wallets are always "in maintenance" or some garbage. Or is that by design so it stays just 10-20 rubes using it? 
Wallet is working on the exchange so what are you talking about?
On Yobit is says deposit is off. I never look at cryptopia anymore because it always in maintenance there as well.
