The best way to stay safe in crypto is be very careful when it comes to choosing a project or coin to invest in. To be careful here means the investor must read and research vehemently on the project in order to ascertain its authenticity and capabilities of becoming successful. Targets during the research should focus on the team and its expertise level, the product, the use case, the idea pf the project etc.
When you have to do so much just to try to not get scammed instead of concentrating on trying to make money with your investments then it is a better idea to just forget about investing in new coins, many do not like this idea because they do not want to entertain the idea of limiting their potential profits, but since my capital is limited I cannot risk my coins in projects that ultimately will not bring me any benefit and not only will waste my money but my time as well.
