While I think the ADA is the most favorable investment right now, and is also one of the hottest currencies, with its recent spike to $3.
On the other hand, MATIC is the kind of network on which Ethereum and Polygon network transactions take place. It’s way cheaper than any other network, with a cost of $0.05.
It’s very easy to use the Polygon network, even some gaming projects like Pipeflare are very popular right now.
Both have their own pros and cons, ADA may have the advantage of being the popular one, MATIC has the advantage of cheaper and faster network advantage.
Prices of both are kind of the same, though ADA is a bit ahead of MATIC, in terms of price. But it’s worth having both in your portfolio.
It’s better to be diversified and own even that currency which you don’t understand, you don’t know when something can explode.
