.. wondering whats the best site to play with this balance.. or do i just need to add more to it just to be safe?
There would be no best site when it comes to gambling because no matter which site you do play if you are unlucky you would really definitely lose.About on your bankroll of 100k sats its never been safe once you deposit it into a particular gambling site. Even you put up 1 BTC wont guarantee you to be safe on gambling.Better out to save that 100k satoshi of yours than on wasting it up on gambling.If you don't like to lose it then better quit on thinking on gambling.
In fact even if you do have 100 BTC bankroll the odds would really be still the same which means results would be always in similar.I agree it your advice that you are just throwing your money on playing games.It is more worth to save up or use this amount for pure enjoyment.The word
SAFE is never been applicable on gambling world,it is way more riskier compared to investments.
