Taking a Bonus at deposit at other casinos will boost your account at first, but you will be: 1. restricted to cash out until you make playthrough 2. very likely be restricted to play at higher stakes 3. might be limited on maximum withdrawal amount
No Bonus casino will always give you 10% Cashback on all your loses. It's pure CASH nad has NO Wagering, so you can withdraw it, if you choose to! it's similar to deposit bonus, but with no limitations. Sure - you would always want to win, but is you loose, there is no better feeling but to get a second chance to try to win.
