I guess this is what happened to me too. When i was doing some research about money making on internet I came across this site called hashocean it was a cloud mining site where you invest some money to buy a hashrate then everyday they pay you back with it. however after 2 years or more this site became a scam. they run away with the peoples money. Then after What happened I continued my research on Bitcoin. After a long run I came across this site where i collected most of my knowledge about crypto currencies.
