as we know in 2017 there was a very popular game called cryptokitties before the market increased very high (bull run) at the end of 2017, then now there is a game that is also popular, namely Axie Infinity and I hope if this is a sign for a bull run that will happen at the end of 2021, so the market can increase very high like what happened at the end of 2017.
I cannot say for sure that the next rise in prices in the crypto market will be at the end of 2021 precisely from the appearance of the Axie Infinity game, but I can assume that 4 years have passed since 2017, and this equals the cycle in the market. So, in my opinion, at the end of 2021, another rise in prices for cryptocurrencies is indeed possible, similar to the end of 2017, but this is probably more due to cyclicality in the market than with the emergence of certain crypto games.
