hmm you got money.
what were the terms of the bet.?
and when was the day you won?
I would never use that sports book again.
Here is why.
They paid you with a low fee on purpose.
They used an RBF style wallet to double spend and send the coin
To a wallet they own.
Ten days later they pay you the cash amount not the original btc amount.
Let me try to make it clear rbf allows a fee to get bumped.
Btc is 50 grand I owe you 5000.
So I pay 0.1 and a small fee like 0.00001
Fees are way higher like 0.0001
It gets stuck.
I look and see in three days that btc is now 65000.
So the coin I sent is worth 6500.
I double spend and do a large fee sending the 0.1 to me with a fee of 0.0002 my cost is 10 bucks. to do this. I send the coin to a wallet I own.
I still owe 5000 to you . but I send 0.077 btc and a a fee of 0.0002
I pocket 0.023 coin but I hand to pay about 0.0004 in fees to do this so I net
0.0226 btc profit.
and here is the kicker.
he paid 0.10001 to to start low fee never going to clear.
btc drops to 35000k. he bumps the fee with rbf feature say 0.0002 and you get only 0.1 btc now worth only 3500
So he can’t lose and you get fucked if it shifts way up or way done.
it it goes prefect sides ways you need to scream and say bump the fee.
that bookie is very likely hedging and playing the game above.
find someone else.
if you could tell us the sportsbooks url maybe no one should use them at all.
I agree with you if this is a smaller sportsbook because I've ran into those instances before where I was always shorted on payouts. And of course they cited on bitcoin price fluctuation. But I don't believe this sportsbook did this intentionally. I've played with them for a very long time and had many payouts....some payouts were much larger than this one and never a problem. So, I'm giving them the benefit of the doubt.
I prefer not to say the name of the sportsbook because I'm still an active player there with a very high balance.
Okay sometimes it is just a coincidence.
