There is no easy way to profit when it comes to gambling, all about luck and probabilities. With bigger bank roll the bigger the chance of winning but still not guaranteed to win. Most people here plays dice and lots of people make money by uploading "safe strategies" on youtube to gain referral commissions.
There is no easy way, I say dude, and there is no way to make profits through gambling so the question of easy or difficult just vanishes. Gambling is all about a person's luck and cheap tricks (skip this one). Always gamble for fun with an affordable amount of loss. That's all to it.
