previously I have never checked the authenticity of a new project address, for now, I prefer projects that have been listed on the market, although the price is cheap but the success rate of the project is clear.
Investing in altcoins already listed in the market is much safer. Currently new projects are too risky, there are too many scam projects that want to steal money of investors and disappear from this market.
From my 3.5+ years of experience, I would say that even those coins and tokens that are listed in the exchanges are also not 100% safe. In the past, I had invested in coins such as BSD and GBYTE, which were listed in the exchanges. These coins have lost almost 99% of their value and they are in the process of getting delisted. So you can't trust all the listed cryptocurrencies. Needs to do research before investing in them.
There is no safe altcoin in this market, only safer altcoins will help you limit the risk of losses. But for the altcoins you talk about, it's only listed on small exchanges, try choosing altcoins at larger exchanges like Binance ...
