New coins or projects in the crypto market are on the bubble, they have not gone through the test of time. The old coins has been in the industry for years and have gained Trust and lots of investors/supporters over the years. They still stand strong and moving. ETH has held it's ground over the years even in terms of the 2nd position from CMC, coins like LTC, EOS, BCH etc are still coins that has good potentials in every bull run the market experience.
So long the teams of old projects are still working and maintaining their projects, they are still worth investing in with the potentials of x50 - x100 profit to holding portfolios.
For old coins, I can only trust BTC, ETH, and BNB. Even XRP has too many risks for investors, for example, the failure to create a new ATH in the 2021 bullrun, while new tokens such as SOL, AVAX, NEAR, FTM have brought huge profits to investors.
Currently, I have no more expectations for EOS, LTC, BCH, although they have existed in the market for a long time, about 7-8 years. Their communities are no longer as vibrant as before because they have not been able to achieve the expected profits, and many investors have become harsh critics of the project team.
I think we will have to accept the failure and gradual disappearance of many projects and tokens in the market, only the best projects will continue to exist and bring value to the market.
