Sometimes im bored at my job and I want to play a quick round of poker, slots or dice. Is there any problem in setting an account with Tor and sending your BTC there and playing?
A problem may be that a tor exit node takes your bitcoin with a scam site that looks like the gambling site.
That's what HTTPS certificates are for. When browsing using Tor, always ensure that there is HTTPS or the exit node will be able to see all the data.
