Granted the wagering requirement of 30x-40x the stake is pretty easy to do, but sadly it seems like betting up to 40x if you only get a $1-$5 reward is it worth it. You don't know that I used to pursue such conditions to be able to get prizes, but the prizes I received were not comparable to what I spent to fulfill these conditions.
It seems that not only me but other gamblers also have the same thought, namely if the bonus prizes that are given are not worth what has been issued then they will not want to do it either.
If you think it doesn't matter how big or small the prize amount is because the most important thing is to try and gain experience then I'm sure it won't take long for you to lose everything chasing a meager bonus but spending almost everything you have in the casino wallet.
I do not run after every bonus the casino offers because i know some of them have tough wagering requirements which are not only hard, but almost impossible to complete. If you are wagering for 5$ reward, you will end up losing your seed money and may not get this reward (even though it is not much).
Talking specifically about Bc.Game will lock your bonus, so in a way it is good. It is better to get the bonus after wagering requirements are fulfilled, rather than getting it before and getting frustrated on losing while chasing the requirements.
