betting is not good a choice .you can invest your bitcoin in a good project, we have many of them.by investing them wisely not on betting or schemes.betting is game of luck,it is not good to start with as newbie
Seems a good idea that newbie needs to choose the better way of earning bitcoin or profit. If they need to or want to gamble, ask them first. But for me, it's worth to try those newbie to gamble but it will be better if they will only gamble with play money or with free trials so that if they lose, there's nothing to worry and feel sorry about it.
