At this point you're probably better off holding. When you talk about swings of that degree of proportionality, there becomes a consensus price - basically a point at which people say "ok, it can't go much lower than this, time to hold/reinvest." For the common investor, the combination of a a downward swing of -50% and the "roundness" of the number like $10,000, created a pretty reasonable floor, at which point things seem to have stabilized. Now if this was a company with that kind of swing, I'd say get out while you still can, but this is a currency/asset -it plays by a different ruleset. My personal theory is the get rich quick FOMO investors will lick their wounds and will buy in one more time once bitcoin looks like it can sustain even marginal growth for more than a month, so I think we're ultimately due for one more gold rush moment (followed by another collapse) before we finally hit bitcoins more "long term value". Just keep in mind that when you follow an all-time high event, its very had to predict what comes next, we're in uncharted waters.
