SBI in general has good and bad points there have only been a hand full of actual real life experiments done and they seem to have a positive impact however they were done on certain segments of society and in certain regions so more research needs to be done to see if would work on a larger global scale. SBI on steemit seems to be a positive move however I have read some negative aspects to it but they were quite hard for me to grasp so lets just go with it for now
