That study does make sense. It doesn't take long to figure out that Bitcoin is the big influence on altcoins in dollar terms.
STEEM's drifted up and down between a range of ~10,000 satoshis to ~50,000 satoshis since November of 2016. The only reason it's above four bucks right now is because of Bitcoin's huge leap.
Bitcoin's still the Big 'B", at least for now.
Indeed, it's still the big king of the hill, for now ;) hehe
For now. ;)
