900 BTG's net worth currently is $100...
15,000 BTG < $2,000

if this address belongs to a dev maybe he had been mining (or buying) these coins for years...
it's a good sign if a dev holds his own coin (if he is not sellling it like many first adopters of centralized overpriced projects do)

usually people tell that a coin is a scam when devs dump all their coins at the beginning and disappear
on the other hand since a coin has been created it belongs to the whole community even if its original dev was not honest

so not a scam, but pretty centralized?
or maybe this big address is an address of Cryptsy cold storage?
