Hi,
I’d like to share a tool called BetMetrics that allows you to automatically import your betting history from supported bookmakers.
So there are people that take gambling and betting so much serious to the point that they want to know their ROI. Since I have been betting, I have many profits and losses but I have not thought of something like this before, although on many gambling sites, you can see your ROI directly and even your betting records for specific period of time.
