Layer one projects – most of them have already made a name. To get a good reward from them, you need to hold for long. It's good layer 2 projects that emerge from some of these good layer 1 projects that have rewarded investors handsomely, just like Arbitrum, Zksync, etc., but even as some layer 2 projects have done good in the past, that does not mean we should trust new ones blindly without deep investigation.
The more we go forward, the more saturated the market is.
And the harder it is to get proper rewards from our actions.
