STEEM did pump in March to April, remember? It went up to 55 cents until it fell to about 35-40 cents and finally to 29 cents after BTC started rocketing. Now it's at 38 cents. I think the first pump was caused by crypto investors finding outdated information put out by Steemit Inc concerning the planned launch of SMTs in March. This is how poorly informed crypto investors tend to be.
Yes, I believe STEEM will rise with BTC and the rest of altcoins. There will be much volatility and many random fluctuations along the way.
