Well, all I can say on this metaverse project was pure hype and it's all about hype. Mostly we heard them on social media because they are actively promoting those projects on social media like Facebook, Twitter, and even in Telegram. There will perhaps be new projects that will have potential but you need research for this because not all become massively have profit as you mentioned OP.
However, you should not rely on any financial advice on the internet, dig deeper it should be the most important part, --and the best of all, invest what you can afford. [as always advised]
Marketing is a bit easier nowadays since people are looking to make money. So, you are in a group of people, who are trying to make money and you do marketing in a way that tells people that you are doing a project that will make them money. This could turn out to be a scam, or it might be a legit project but no matter what, the marketing is easier nowadays.
You spend some money and there are some KOL and there are some places and if you spend enough money to be featured in all, you are going to be known and people will throw money at you. It could be meta, it could be nft, it could be just a meme token or even just a regular coin and you will gather a lot of funds.
