.. wondering whats the best site to play with this balance.. or do i just need to add more to it just to be safe?
I recommend to you to exchange 100k satoshi in dodge coin and play dice game in fortunejack. You will generate huge amount of dodge and i see that having huge amount of capital is much lesser the risk you have in rolling dice but dont be too greedy like what they said there is no safe way on playing in gambling.
Why need to waste money in exchanging for another coin when you have a small amount?
Just chose a site which can accept your small amount deposit and also check what is their minimum withdrawal. If all okay for then just go and enjoy your free time because it is not a that big amount. Good luck to you.
