yes, polygon or matic is worth investing in. Since many companies are currently developing their projects using the polygon platform, I see from this perspective that polygons will likely be more valuable in the years to come.
For this year, there are not many new projects that use the Polygon Network, but in the future it is more likely that polygons will get a lot of glances from investors and project developers as well as from day traders as well because everyone wants to benefit through Matic and the use of Polygon.
Not many projects under matic because it's new, so as an intelegent investors we should see the potential projects before it going hype.
Right now matic network is one of the best and for me personally the most used for doing transaction because very low fees (even cheaper than bnb) and quite fast transaction speed, but i'm sure the fee will be increase if the network become more crowded in the future.
So it's still worth to invest right now.
