If u found new gambling website and want to play on it first time. Will you try to find some topics on forum about this website before deposit money? Or no? If this website looking clear and you liked it?
I sometimes. But generally no..

Yes of course. This is the first thing I do when I send or invest my money in anything Bitcoin related, even gambling. I check the forum, I Google it and I read the reviews. Bitcoin ecosystem is full of scams at the moment and everybody need to be extremely careful.
I would suggest too all the people our there to do the same and take time while investigating to whom are they sending money to.
