Any sphere of business has its own pros and cons. And crypto gambling is not an exception. Actually, I’ve seen an article, focused on this topic —

From what I’ve learned, crypto gambling has following bright sides:
— fast and cheap money transfers;
— anonymity, as it is hard to track transferred funds;
— pleasant bonuses.
Speaking of downsides, I think I should mention next things:
— there are some unpleasant restrictions, for instance — rollover (necessary wagering before withdrawal), deposit limitations, time limit, and game limitations;
— withdrawal conditions may vary from one to another casino.
So, answering your question, I'd like to sum up — the usage of bitcoin casinos is almost identical, as you would play ordinary online casino. Though they have some distinctions, the principle is the same.
