I'd think that one good step towards quitting would be to stay away from other people who are gambling.
That method of quiting gambling really helps a lot. If more people decided to do this method then there would be a lot less gamblers right now.
Then again, its pretty tough to just state that someone shoult stay far from the people that are usually gambling because Bitcoin gambling is mostly done online and staying far from the people that are usually gambling would mean that the person would have to stay off the computer since mostly everyone involved with Bitcoin is gambling.
