Just an "FYI" - I live in Australia and we here in Australia don't write numerical values in that way.

The OP didn't claim to be from Australia.

Nevertheless it's bullshit for many other reasons, e.g.:

You are depositing money direct by broker without sending to me and cannot be withdrawn anywhere other your wallet so I cannot scam you.

Doesn't make sense that it can't be withdrawn.

Also offering $50k "interest" for a $50k loan is absurd. Clearly looking for greedy idiots.
