Bitcoin Forum

It is evident there is a bright future ahead for bitcoin in the gambling industry. Particularly bitcoin-based provably fair gambling has become  a lot more popular throughout 2017. Casinos and gambling platforms dealing with cryptocurrency offer many different benefits, that much is certain. Over 1 billion bitcoin-based bets were placed with bitcoin through March of 2017, which is a spectacular number.
There are plenty of reasons as to why people switch to bitcoin casinos. First of all, the vast majority of platforms focus on being provably fair. In doing so, these companies ensure players can manually verify the outcome of every game. Ensuring the casino doesn’t have an unfair house edge is of the utmost importance. Traditional casinos cannot provide such unprecedented transparency.

i have to agree that the provably fair- is a main factor but there is also another item that needs to be looked at with the same perspective. and that is the KYC policy . the vast majority of frequent players prefer to stay with their names off any website and when there is a good playing field and they dont have to post their name it makes for several players to have that as preference also.and this is also something that a traditional casino cannot offer if you make a win over a certain amount! plus while trying to receive that nice lil win your data is transferred directly to the IRS if your in the USA double whammi in my book! i have had several large wins on several different casinos and each one did almost the very same procedure! so at tax return time  dont expect to be sliding by without a nice lil audit! KYC?  so sorry but i will pass.

You can always check/scan the terms and conditions of each bitcoin casinos to know if they would perform kyc on their players (so you could avoid such casinos). They do this kind of verification because they might be regulated by their local government but take note that not all bitcoin casinos are regulated.
