I could never make that wallet work, and I never trusted it. So confusing and I was never able to receive any btc from the forks I saw my balance there....
I have managed to send out of it, but you're right. They're not to be trusted and it's a very stupid set up they had.
They had an in wallet exchange that was pretty much the only place to get rid of many of them. They pulled it with no warning whatsoever. That says plenty.
Only stick your junk keys in there after anything else with any value has been moved.
Time is essencial when claiming those forks. That´s a problem, because good wallets (or at least functional wallets) take some time to support those forks. THen you have to go to shady wallets and shady exchanges to trade them... but most of the time they are worth claiming if you act fast. Look at OP prices, there was quite some money for a full btc.
In the height of fork season there was a guy on a Reddit sub devoted to forks signed up with all the piece of shit exchanges and running scripts that could move some of them shitforks. He dumped on your behalf and took a cut. I should've used him.
