I would say: make a plan. There is nothing wrong with making a quick move, as long as yo know where you're going. The risk is that you might need to rethink your plan if the market is against you. Case in point: about a month ago I was looking at the eth/bts pair on openledger. It was at 4000 bts. I was millimeters away from sacrificing the eth I had. The crash happened, my plan is still to get as much bts as possible. I recently sold steem to make it happen. Not much, but at a decent price. But to sell off eth to get there at a 1000 is not good enough trade. There are endless possibilities.
