My brother recently invested in the Blockchain and has delegated his 600 STEEM to Minnowbooster. His return on investment is 0.45 SBD per day at the moment.
With the current price of sbd, he is probably going to get half is investment back before he knows it
I calculated it's about 75% in a year. Under current circumstances.
and he don't have to do anything, with time he just have to convert the paid sbd to steem and power up adding more power to his profile.
Money spent well
He will compound it indeed. It will all stay in the system.
