.. wondering whats the best site to play with this balance.. or do i just need to add more to it just to be safe?
All the famous gambling site safe to deposit as you wish but not safe for the fund it will be same amount once you started playing in that site. There are wide range of people lost money only instead seeing the profit alone.
If you want to invest for sportbetting you go with the sportsbet.io, nitrogensports.eu and OneHash.
Dice game I suggest you to go with the duckdice, bustadice and primedice.
