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.
