Simple answer is to stop following new projects, or to atleast be cautious when it comes to new projects. New projects are not perspective in this moment maybe, so it's best to invest in BTC or top alts at the moment. But in the future there will be time for new projects, I'm sure in that.
Just to be safe it is better to invest in top coins these days in the market. Actually we have many options on what project to invest our part is to do your own research this is really helpful on our investment. Some new project are rugpull, they just collect funds or scam money from investors. Never invest without doing a proper research without it your money will lose.
