@cocopop3011 the issue is not just currency but the size of the bet too. So in that spreadsheet please keep track of bet size too.
Like for example it's okay if people are playing in 20 cents euro, 20 INR, 40 cent NZD, 100 myr and so on. These are different currencies with same value. People are playing with different currencies but there is no advantage here.
The issue is one person playing in Euro 20 cents and others doing- .20 NZD(.10), 4 INR(0.04), .20 MYR(0.04) and so on.
