^ Definitely right, for me, if that gambling casino site was operated a week ago, I will not trust them to hold my fund.
It is good if it took months or years before you will trust them because of that length of service they have, entrusting funds is very important because there are products that are fake. Another solution is to do your own research at the last.
A small amount to deposit and to test them out is totally fine, that's the purpose of testing them. A few amounts to trying your luck with them to have some review is just fine.
But most of us doubt entrusting them with a lot of funds that we usually do as bankroll for the casinos that we know.
There are gamblers that do this thing to test and deposit but, there are new casinos that are also giving out free rolls, tickets and funds to be tested by common gamblers which is their target market.
