The pull of BTC on STEEM has been on par of the pull of BTC on Ripple. Ripple has gone up by a factor of about 1.6 only since the December 2018 lows. STEEM has gone up by a factor of 1.7.

In terms of price action STEEM has always been something of a laggard compared to BTC. STEEM remained in a rut also in the autumn of 2017 while BTC and the other leading cryptos were surging - until SBD exploded in November, followed by STEEM in late December. Also, STEEM plummeted to its all-time-low in March 2017 while BTC had already started moving upwards. STEEM's got a life of its own.
