Sometimes new coins invest are risky but not every new coin, you know some new coins already entered top 50 to 100 ranking in the market in too short time, how it's possible if their project is not potential or strong fundamental, currently so many new big projects in top ranking like ARB,SUI,ZETA,TIA.
its because these project backed up by big ventures or investment labs, i've seen that most of the project backed up by these never turning out to be scam, the value also usually climbs up despite giving away massive airdrop they instead become successful and known by a lot of people until now ARB is among the most used L2 ever for practical things, excluding those L2 that currently are being farmed for airdrops where they incentivizes the use of their blockchain ARB instead still have so many transactions as well as dapps deployed within the platform, it goes to show its success.
if its random new coin that aren't even backed up by venture capital or at least some popular cex i believe the risk increased by several folds, also the overall price in the future might not be as good as the one being backed up by big venture.
also, in raising price, the name of the venture backing it up also a huge factor to determine whether people gonna buy the coin or not its overall like riding on these big venture capital names.
