Maybe you can add this suggestion,
Avoid new coins if you wanna trade in the long term. Although listed on the top exchanges, it isn't uncommon for them to actively engage in fraud in terms of price manipulation and trading volume.
agree, many new coins are falling in price and for the long term they cannot continue to develop due to many reasons which makes the team leave the project
Long-term investments must be made on top altcoins
People who are aiming for long term investment should always go with potential altcoin which is actively trading for more than 3 or 4 years. The new coin is very risky which we don't know whether they have the ability and skills to develop because potential coins are still trading on the market because of active technical developments.
