A simple example is at https://boxmining.com/outbreak/
Michael is kind to help everyone get valid information about the pandemic, however one post on the page is targeting people who don't know about bitcoin mining claiming they can make much larger profits than is reasonable. Just email a guy who only calls himself Mining Expert bitcoinminingexpert11 @gmail.com and doesn't talk like he knows about mining. Just send them money so he can acquire things like GMO miner B3, and you'll get great returns in 72 hours because of his expertise in solving the difficult algorithms, yeah right.
