Keep in mind that the fundamentals of Bitcoin hasn't changed since this downturn (I won't call it a crash or a bubble burst because of this reason.)
All that happened is some "investors" got spooked. If you got burned by recent events, then I'm sorry for your loss but you' re a crappy investor. Don't give up your day job (maybe one day you'll be paid in Bitcoins and have some.) Bitcoin is not an investment vehicle, it's an exchange commodity. Go back and read more about Bitcoin basics, it's not rocket science/brain surgery.
Bitcoin's value to other currencies is irrelevant. Since Bitcoins are infinitely divisible, you'll always have some no matter where you get in (don't let the 8 decimal places fool you. When we get there, we'll just adjust the protocol to add more decimal places, just for you Johnny-come-latelys.)
Bitcoin's amazing attributes over all others forms of currency is still there, unlike social fads, fraudulent/bad/unsustainable business models, third party controls, frauds, confiscations, regulations, etc. Typical crashes and pops are usually indication of a significant underlying change of your investment. A company forecasts slow growth and all hell breaks loose. Bitcoin won't (and shouldn't) suffer from this because Bitcoin fundamentals and attributes haven't really changed.
Bitcoin is what it is ... always ... just as revolutionary today as it was 4 years ago and that's why this blip will be a distant memory very soon.
So, chillax people. Bitcoin ain't goin' nowhere.
As for you greedy people out there, you're doing it wrong.
