Hello @walter2021 ,
Thank you for submitting homework task 5 ! It was a good read ..

Podemos ser estafados por empresas por el poco conocimiento y la ignorancia de la minería en la nube

Actually any one can get in to these scam cloud mining platforms .. they usually give higher profits in first few payouts to make more people to invest in the platform. They the leave suddenly taking all the money. so we must be very careful .. nice work [4]

Thank you
