Investing is not about the network you choose, but whether it is legit or a scam.
well frankly the blockchain itself does affect the investment sometimes, you might figure out that the project deployed in ethereum have higher chance of being successful than the ones being deployed in BSC.
even many considering BSC to be meme coin and shit coin infested blockchain in which definitely gonna reduce the rate of success if a project is truly committed with theirs.
in the case of base, the fact that its new blockchain thats currently in trend, easily make it center of attention nowadays that some projects that deployed their in base definitely got free marketing here.
so where the project is being deployed does indeed affects a lot in this case, even more if its newer coins that needs to garner attention so that it could grow.
certainly you won't be deploying your project in some random blockchain and hope it will turns out to be success.
