I think it is a foolish idea. For several reasons. You will end up wit coins that has no practical use, except from sending (hopefully) them back and forth. And if lucky they have even made a wallet that works. The cheapest coins will be listed on exchanges with little volume and can prove to be hard to get rid of.

Do your due diligence:

Is this something that has a use case except from only being cool?
Does the software work?
Is it traded?
Is it unique?
Are the developers active?
Are they funded?
Do they enter harsh competition?

I expect most of the low-low-cap blockchains will not exist in two years time. There will be new ones, sure. But there will be fierce competition for the top spots.
