I'm guessing STEEM will pump 100-fold from it's previous bottom like it did last time while BTC will go from 3000 USD to maybe 180,000 USD (or multiply 60 times in price).

Go ahead, sell your Steem. What are you waiting for?

But I wouldn't buy STEEM right now if I had some fiat to spare. I'd buy BTC because BTC is always the first one to emerge from a bear market. I'd wait for BTC to reach its next peak and only buy STEEM then.
