In gambling it can happen too if you go and play in the first casino you find online without doing research first or seeing reviews and feedbacks about the casino.
Thanks for your clarification, i think the first thing for any gambler to do before embarking on gambling should be do a research on the casino before gamble or in the same vain check their feedback for clarification either to gamble with them or not to. Haven't seen much greediness among gamblers except from the amateur ones which cannot be said that, gamblers are dumb.
You got the right. Make research will give you an answer if the gambling site is good enough for you to play or not, and besides, you can play without any worry if the site scams you. But I think if you can see on here, you will find so many gambling websites which many members recommended because they already use the site to play for a long time before.
