Often as a newbie, when you see a new project you are tempted to invest in it. Why I agree that not all new projects are scam, always ensure that you do your own research before putting your hard earn money into a project, otherwise you will wake up to discover that the devs have disappeared with your money.
I have a personal experience, a friend and a mentor told me about a new project that was looking very promising, he advised that I invest in it. So, I did even without doing my little investigating, not too long, the dev pulled out liquidity and that was the end of the road for the project.
So, that's how I lost my investment in that project, though I didn't put much, just about 10$, but a lost is a lost.
Please, be careful out there, the devs are not smiling
And if you must invest in a project you are not too sure of, always put something small, don't go all in, you might end up regretting.
Don't invest where anyone advises you to invest. There are many dev teams who will beg you to invest in their project through PM but you will never invest there. If you have to invest, you must first notice whether the coin is listed on the best exchange and then invest there in a small scale. There are many scam dev teams that will advise you to invest and always tell you positively about their projects. Make sure you don't fall into their trap. Invest from where there are good mediums to invest.
