It is of no surprise that even in 2019 the gaming industry has not found its touch with Bitcoin or Crypto Currencies in general. There are many reasons for them not indulging into the crypto market though.
The crypto currency market is highly volatile. The prices fall and rise too often and that is dangerous for any business accepting them as a mode of payment.
Steam tried to give the crypto game a try but it badly failed because the transaction fees for Bitcoin rose from $0.20 to $20 in just a week.
Although all these factors hinder the gaming industry from including crypto into their systems, I am pretty sure something is being worked on to overcome this problem. After all, the world is now adopting the inevitable phenomenon that is Bitcoin and Crypto.
Who said so, I think that the gaming industry are even the ones that has accepted the use of cryptocurrency more than every other industries we have there, let me mention some of the big games to you, such as BMI Gaming, dice, craps, keno, video poker, roulette and many more, they all play these game in bitcoin now, so they are gradually expanding, they might still be few but their number still corresponding with the level of acceptance of bitcoin generally.
The more the adoption of bitcoin grows, the more some of these gaming industries will also start to adopt the use of bitcoin for their game too, so we should just look at the future, majority of them have plans for it, but they are just trying to watch as things takes its shape in crypto generally.
