Perhaps. Awfully interesting coincidence timing-wise though.
I also made a mistake. It isn't BUSD - It's USDT (Binance Peg).
That campaign has been scheduled to run weeks ago. I've been in communication with that project team for weeks.

It just so happened that they have sent me $4,400 in USDT (BEP20) ($4,000 for the bounty pool and $400 for 4-week campaign management)
[TXID] few hours after what happened with the Electrum wallet.
Why would I take $5,000 and put it again on a bounty campaign wherein all that funds are just going to be distributed to all who participated in it

I tell you now, I'm no Santa.
