Which one hast the worst future?
Polygon (MATIC) have a good future as a Chain provider. Transaction fees are very low on Matic Network. So like BSC it is also widely used now. So Matic is steadily gaining popularity. On the other hand Moonbeam (GLMR) has also brought its own network to the market. Which is still not that popular. But maybe in the future it can do something better.
