Not especially exclusive to crypto casinos, but casinos in general. Ideas that make it big elsewhere are copycated all the time. I guess you'll know this only when you try all those shady online casinos that are out there, especially in China or Philippines!
Personally I think copycats are in every industry. If you have a mobile app and you don't want to pay, and are forced to watch ads, then you know what I mean. Thousands of ads all looking the same as each other.
Same as going to Google Store search 1 app, see 100 copies.
This happens everywhere, if a product which is innovative is released and people are buying it in just a few days hundreds of cheap copies appear on the market, but this is stifling innovation as those people need to pay all the research costs and when they finally have a product they can sell it is immediately copied and they are not paid any royalties either, so I think this is the reason why no one is taking any risks as it simply makes no sense for them to take them.
This is in fact reality on which if there's something had been successfully gaining or getting some attraction then this is where other people would be tending to copy it out and believe that they could get somehow
some market share when the trend is still in going until the market would be flooded out by similar projects which ending up on being saturated and people who do engage on it would flock away into something new.
Innovation is really limitless yet ideas and other concepts would be made out but no one knows on when it would happen.The first in the market will always be getting that
attention and recognition and this is what other people been trying out to made on.
