Allow me to combine those 2 posts:
they sent the BTC on the wrong network and Binance cannot recover the coins.
But if they did not send it on the BTC network then the coins are probably lost forever.
This is utter BS! Binance made up their own tokens that they sell as "equivalent" for real Bitcoin. Binance also owns the real Bitcoin, and they can do as they please with it. If coins are "lost" on their own chain, that would mean Binance takes ownership of the equivalent amount of real Bitcoin!
I wonder why binance put BEP2 and BEP20 above Bitcoin Chain.
I'd say the scenario above explains it. Did I mention it's
an exit scam waiting to happen?
