I prefer old coins with strong fundamentals to invest in when the market is down. new coins run the risk of being useless and valuable and difficult to recover. we'll see how many coins in the pancake lose their value even die.
Even on my side, new coins which are good for short-term investment and are very risky might become a shitcoin after it's been listed.
Top 10 cryptocurrencies in the CMC that has a high volume which is considered good for a long-term investment, beyond that, you need to study and monitor its progress.
Just listen to the trend and always have your own research on it, IMO, the ICO's that has a good return is on the gaming sectors or those coin based on games.
@OP was right and I tend to agree, find your own research first before putting an investment.
The current market situation present an opportunity to research properly and invest wisely, take notes.
