It is really hard to safe gambling because you will spend a lot of money with it and that is bad because if you lose that it would be all wasted and that must not happen to you.
You can play with some small amounts if you dont want to lose that much money but the chance to win is also smaller.
Yes, those people who do not have any experience with gambling and want to know a safest way of gambling then for them the safest way is that they should not have to invest large amount on gambling but have to invest minimum amount and have to play only for entertainment.
I think even if you use a small amount. it will not prevent you from defeat? in fact you would be more willing to take risks when it uses the same small amount. there is no safe method
