The Sandbox is awesome and it's honestly one of the coolest projects in crypto. I have no doubt that it will be successful and provide players with a fun way to game that also incorporates their favorite hobby, crypto. However, $SAND as an investment has been pretty rocky. It's one of the most inflationary coins out at the moment, and the team gives them out like candy to accounts that engage their platform. Not to mention the high staking rates, etc... The downward pressure is crazy on the price of SAND. I'm sure there will be people who get rich catching the bottom and staking, but for now it appears many more people will lose a ton of money until SAND has been widely distributed.
I'm not sure that the fall of SAND is caused by the distribution of many tokens, if we look at the entire market, we see that the entire cryptocurrency has fallen by 90-95%. I played it and participated in Sandbox season 2-3 I am very pleased with the game, I will enjoy playing it.
