i dont know that.
its better to used other exchange, like binance.
dont used btrex, they had made more coin delist, many trader disapointed.
i agree to the team btg that din’t pay them, because, its happen at the exchange, they serve their wallet without any securities and pashprase to us, its mean we dint have the authorities, and the btg team didn have the network (i mean the network is being us that used btg in the world). in case, when the exchange had attack or that coin being hard fork…we can’t save, spend, send the coin that suspend to other our wallet…
in your case… thats enought to know them, they are not profesional with their exchange. if they profesional…they would like to help you to WD. this mean…its bad for you, you lost your btg.
