The world is not out of ideas or solutions but the main reason why there haven't been any good projects for a while is due to the fact that most of these new projects lack proper planning. Nowadays projects are just interested in making profits rather than providing solutions to address specific problems seen in the entire ecosystem of the world. Project managers and developers need to focus on providing solutions rather than having a profit minded interest.
Now the market is crowded with people who just want to make money but not to improve the world of cryptocurrencies. we cannot stop these people. we can just choose really useful projects and invest in them
after all there have been many old projects that have proven progress, if you are still looking for new projects which of course it will be difficult for you to research them, then investing in old projects i feel is not a problem, because so far even though their prices have dropped but that does not mean the project will die because there is still a very good recovery phase for long term investment
