I'm not sure what's going on here so I am posting this topic. I lost some money but as long as we can save someone else from falling for the same scam it's all good.
Yesterday I had someone hit me up on Discord asking to have their Bitcoin exchanged for any other token. I agree even tho the amount was below my minimum. After waiting for a while for the other party to send the Bitcoin I get a phone call and need to go out. About 30 minutes later I get sent this screenshot:

At this point I'm out and can't send what we agreed on back for 1 reason:
1. I have no access to my wallets so I can't see if the other party has really sent the coins.
After getting spammed for hours with infinite messages and missed calls which were mostly made of threats about bad reviews I go back home and open my wallet to see that there is nothing in there.
I let the other party know about it and I get sent the following link:

e5e783122e3c2dcd3b4ec3b1ed5533fe3b0438512c5597625351d0f108737c7f"
Meanwhile this shows up in my wallet:
Luckily the scammer wasn't smart enough to gain my trust and make 100x that amount.At this point I'm confused and the most I can make out of this is that this is a double spending attack of some sort.
Now what I'm left with is the following:
