What is your opinion of POLYGON-MATIC cryptocurrency?

This has experienced more than 50% growth in last 36 hr, when everything else is going down. As per information available on their website, it seems to piggyback on Ether and does some technical mumbo Jumbo to jack up the number of transactions possible per second. I am not technically competent enough to seperate the corporate talk vs technical reality. Grateful if the experts in the forum throw some light on it.
