Interesting theory, i think there is certainly a link between people cashing out of SM and steem drop as theonly way to cash out is buy sellingdec/cards for steem (off the exchanges) then dumping the steem and the price drops. I think we are in a downward spiral though, people are selling as the price is dropling so fast, i dont personally want to hold steem anymore, it seems if you hold for more than a day or two you end up losing a big % of your money. It could be the end of days for steem. Its going down and its not slowing down. I hope not since im so invested in it but everyday it looks more likely.
