$100K is a serious number no matter where you live in the world.

At what figure do you think they'll look at it and say "Hmm, there's something not right here?"

You've reminded me of an acquaintance in Sheffield. He had a smart guy working with him and they'd calculate the probabilities of casino bonuses. So he'd pay students half of the profits (usually around £1k - £2k) and made a small fortune - paying off his mortgage and renovating his house. (The casino "reinvestment" rules are huge multipliers now to make it unprofitable.) He also gave us a tip once about a Greyhound in a race in Sheffield. I got on it early at 6/1 (£100 I think) and when they set off, it was odds on. It won by something like 16 lengths. Bet365 limited my account to 10p per bet after that.

He was a character but I digress...

I can't remember what happened but he ended up getting scammed out of a large sum of money by some guy in Costa Rica, so he flew out there to get his money back. When he turned up to the scammers mansion to find numerous armed guards, he decided it might be best to accept the loss and move on!
