How relevant are blockchain games and is it possible to make any profit on them? By 'making any profit' I mean an alternative to trading, mining, etc.
Well, you must lose some to win some, and I can assure you that all those games will never go without asking you to deposit some certain money. I know of casino, that is purely a gambling game which a site has been created for people to come and bet with cryptocurrency, so it is not like they are earning cryptocurrency free, they have to bet on casino and they the winner goes with the cryptocurrency used in betting, and some of the other games that are giving free crypto might be giving out very small amount of cryptocurrency just to encourage people or attract people to the use of the site to play game which must definitely stop after they must have gotten some users or gamers enough on their platform for their services to keep running.
I played some crypto games and was able to earn some crypto. I think this is a good way to earn cryptocurrency, but it is not a substitute for trading or mining.
Could you please elaborate more that where you are earning and how much are you earning. I believe many people here are looking for all new opportunities to earn more. I had already come across many crypto based games but none of them are worth for the time and efforts we do spend for them.
