lagit and long lasting mining of a well known project. mine and ear polygon (matic) on the go
polybox is great and yes you can withdraw,
i use trust wallet for withdrawal, and withdrawal is also fast it take just a minute or two,
but the community is in doubt sometimes but since i can withdraw the matic into my trust wallet i invest anyway.
If anyone is interested u can use my link
