Why would you buy either one of them? both are inflationary. What don't you understand? Is it so hard? I've never bought Steem, I've only earned it, there's no point at all to buy Steem. SP is even worse because it's still inflationary and you are locked for 2 years into that. It's like you are trying to sell me US dollars "to keep the economy up". Don't tell me you need to invest money to win more because we know where that discussion is headed...
