Agreed it all depends on how and when bitcoin runs. If bitcoin goes to $500k then Polygon can easily go to $20, it would be an almost equivalent increase in price. Definitely a bright future ahead for polygon but calculating usd is difficult because a lot of it depends on the bitcoin usd price.
Polygon has different natural and many time its price remain stable with the increase of btc price but still i am agree with you. when btc reach 500k that's mean a large money will be entered into crypto market which will also migrate to top 10 coins and matic will be best choice for trader but this will not in short term because there is no sentiment of happening this. despite btc price soars to 30k ,matic is still struggling Below 1$ which show the less interest of buyers.
I guess it have something to do with the fact that there has been lately many coins released thats all about smart contract blockchain that I think it gives some negative effect towards the existing coin with smart contract niche.
these will definitely take up some market share of the existing coins like matic, though there's no real proof about the correlation i think it might be the case with matic nowadays.
moreover the fact that matic total supply is simply just too much kinda speaks volume why the coin itself hardly rise, it'd be far better if they could have some kind of event and some programs that could help reducing
their total supply through burning their coins.
