Most of those projects are dead and just floating in the space to disturb other good projects. The funds used in most of these projects would have used to invest in a profitable projects. There are sometimes greediness also made them to create and launched these projects. I also checked the website and it is active but I don't know if the market price is good for people to use the service because in most cases and why people are not using DEX is because the price different with CEX.
The best time to invest is the dip and hodle for a long term investment. and now that the price is decreasing is another time to prepare the portfolio for the next ATH.
While the best time to invest may be when the market is down, knowing where to invest in matters. Because when there’s a dip, even shit coins get dipped. But that doesn’t mean it’s a good coin, the whole market is simply affected. So knowing where to invest is really important and in fact, more important that investing in a bear run. People still make money when prices are high because they know where to put the money.
Investing in trusted coins is definitely a successful investment, and you can see that as many whale investors as possible always make money from the investment. And especially trusted coins have the highest dumping and the highest pumping, so considering these times you can definitely invest in coins to get the most success. But I think it is useful to invest only in old and trusted coins and not new Altcoin coins but have their own risk.
