Once I was a high roller, and used to spend upto 0.1 btc per roll. Most of the time maximum roll value happens with martingale strategy. I encountered a massive loss out of gambling and the same has made me go low on rolls. Right now the maximum bet value doesn't exceed $10.
Today read about a person winning from
chips.gg having a bet value of $400, and a misclick getting him a winning amount of $19800 on Dice. Maybe some day I need to be such a high roller with high percentage of luck.
Man, gambling with 0.1 btc per roll? You must have loads of capital that you can dispense with. Usually when I gamble, I set a cap of around $100-200 for the whole game. I usually allocate those funds equally, thus most of my rolls are relatively low. I occasionally win but when I experience some loss on the round, I try my best to recover such loss. But when my loss exceeds the capital that I initially set as my limit, I tend to stop and call it a day!
Well again, gambling is gambling. Sometimes you get extremely lucky in a roll and sometimes you lose a significant amount of money in a day. As long as you are willing to shoulder that loss and it does not hamper or prejudice your livelihood, then you are good to go.
