For me, investing in game projects has always been a very risky business. I don’t want to say that game projects are not capable of bringing a good profit, I’m just saying that it’s difficult to find exactly the project for investment that can become popular among gamers and generally be able to release a good and popular game.
But, consider this: how can you make a profit without taking any risks? Although investing is always risky, we can mitigate this by thoroughly researching the projects, vouching them, and determining whether or not they are truly worth it in order to reduce the risk a little bit. When it comes to investing in new gaming projects, you must go first before others in order to make a profit. Most people are aware that this is a trial and error phase in which they must predict whether a game will become popular or not. Just make sure you invest only what you can afford to lose and don't put all of your eggs in one basket at the same time.
Going first or investing as early as possible can be both risky and rewarding. Risky because they can turn into a scam immediately but if they are legit and they got boom, your going to earn huge. There are games that got boom and then later on they became weaker, that is why determining things like you said is important.
If we think they can collapse soon, we should not wait any longer, let us not be greedy for earning more. It seems that the guy above you is looking for a perfect investment but there is no such thing as that because there are new projects that are coming out regularly and they can be better than the previous one.
. Good Luck.
