I wonder how YAY Games is gaining popularity so rapidly. Not long ago nobody had even heard about YAY Games and now its 24-hour trading volume reaches more than 1M dollars
Now again the trading volume has decreased, I just checked and saw that the trading volume is half of the amount you mentioned. There is a hype of gaming in the current market which is causing some gaming related projects to get some attention, but that does not mean that they can stay in the market because of that hype without being listed in any big exchange.
So if you want to get volume, you have to list big exchanges and create marketing strategy differently.
