From the reviews you make of course it is very interesting to play blockchain games but the problem is we have to spend a lot of time to stay in it, and this will certainly be a problem for each individual to increase the revenue of the game, although we have a high probability to be able to get maximum results but we also consider the time we have spent ,but we all have different missions in getting results in the crypto world.
You are right that it may take a lot of time to get good profit from playing blockchain games. But not so rarely there is a chance to get some good profit just playing game in case you play the beta version or just at the very beginning of it's creation. Of course the more popular game becomes and the bigger amount of participants plays it, the harder to get high reward for playing it. From time to time I play blockchain games. And you know there were a couple or so where the reward was not bad, for example an Ethereum or a couple of ETH. It was in 2018 and the price of ETH was lower than nowadays. But nevertheless it was in real. There were some games that gave not so high reward but it was a bit pleasant. Everything depends on the game itself and creators' readiness to give high rewards to participants, and everything depends on personal requirements.
I've pleased that I've already overgrown all that and now prefer trading crypto to sitting in all that Blockchain games.
