At the moment investment in new altcoins is very risky and you might end up losing your money. It is always better to invest in established projects that have survived the market for many years. It is better to invest in ETH, XRP, LTC and DOGE, compared to new coins. Although the ROI might not be very high, your investment will be somewhat secure. The majority of the new projects are actually cashing out the market sentiments.
Market cap/ price does not determine the success of a project and should not be considered as a standard to invest. High market cap coins such as LUNA have failed miserably and people have lost billions. So was the case with FTX. In the past, we have scenes that most projects with a potential wiped out from the market. So, it is better to research before investing and try your luck in more established coins.
