For me, I can see the next cryptocurrency opportunity is a "problem solver".
A project that solves the problem. Most of the cryptocurrencies we have right now are don't have yet any working product, or still not used in real life which for me is a red flag.
So my recommendation is a type of project that already have a "working product", good tokenomics and it is solving a real life problem.
I've seen projects in the past that has a use-case that's very beneficial for us.
The only problem though is that, either they have a small community thus, it failed because of lack of support, or the project rug pulled including the money that they have.
I believe that in the future, there will be projects that will be beneficial for us in our every day lives. I don't know what, but I believe that there will be. The problem with some projects right now is, they are focusing more on the money than on the project. We've seen projects that are asking for money towards the investors, and in return, they will create and develop the project. I mean it would be better for us, and for the developers if they will create the project first then ask for money to us investors. I just hope that there will be changes in the future.
the truth is, we have seen a lot of promising projects in this forum alone. before, i used to check projects in the ANN section. but lately, not really keen on checking them out. most of them don't have sincerity when it comes to implementation of their objectives. just quick cash for the dev/s pockets.
so if you want to have a lil bit of assurance that you will invest on a valuable project, better check in the top alts and see how they are doing with their developments.
