Simple avoid them. That could be the only solution. New projects are for them who have deep knowledge about them. Although that type of investor also get scam even after that much qualifications and knowledge. So newbies are much helpless and one step ahead of being scam from those professionals. So buy old coins which growth percentage is good since launched. Go to cmc or coingecko and pick your choice among top20/top30. Memecoins like doge, shiba are better to skip
The very simple first step on how to avoid being screwed over the net is at least search a lil bit about the project.
Because in today's internet, you can practically search for anything. So you can already get a lot of feedbacks or reviews on a certain topic.
As to move forward, at least give yourself a lil bit of time to assess the project itself and not driven by the fud surrounding it.
A lot of people are jumping on the hype because they believe they will also have the same fate of earning profits as claimed by others.
The rate of scam projects in the market is too much and that is why many investors had decided not to invest in new projects because of there experience that had made them to lose huge amount of funds in the market as a result of investing in the wrong crypto projects.
For us to be save as an investor, there is need for us to keep doing consistent research so that we can know what project will be profitable for us.
