All gamblers also know that when you lose, money cannot be recovered but you have to gamble again with greater luck, so indeed all of that must be carried at a very large risk, I think the OP is happy with the site they are playing on, see there are many types of games that we have to try, maybe from some of the others we can be lucky and return our money, but that is also not with ambition, sometimes people always mistake their emotions.
If it is comfortable on a particular platform I think he will stay there.
Sometimes we just need to try and trust to see what each sites can offer or we just need to be contented or get familiar with in where we play and what we do in a certain site or even in sports. If OP see something better he will sure transfer in it but only time and situations can tell upto when and how to do it. As long as he don’t see any fault or he already won in then it’s fine but we should always be careful in putting too much money or we must know when to withdraw and what to if we see something suspicious.
