I follow a strict bankroll these days so my max bets aren't a lot. Something around 0.1-0.3. Can go up.
But in the past I have gambled upto 14 BTC on one bet.
14 BTC ? That would be 6-10 months salary in my country, I would have converted them to cash and enjoy a nice vacation a gift I would have gifted myself. By the way you must have a lot of money to bet that huge amount on a single bet. Hope that it ended up well on that day when you gambled 14 BTC on a single bet.
You are right 14 btc is somewhat 8-10 months salary on my day job. If i lose that amount for sure i would cry. I would rather spend that on some useful things and dont bother to risk it on gambling on a single bet. I usually bet 0.001- 0.01 when i do gambling because im afraid of losing huge amount of money.
