Some comments here:
1. If you are new to #Bitcoin and worried about the unexpected drop, welcome. This is your baptism of fire. It will happen many more times. Relax, take a deep breath, enjoy the sale, and accumulate more.
2. The BTC from Mt. Gox, an exchange that went bankrupt in 2014, are moving, and it is likely they will start selling large volumes, which could cause a strong price correction. Again, enjoy the sale!
3. Before complaining, take a moment to admire the fact that #Bitcoin allows billions of dollars to be moved uncensorable in just a few minutes for a $3.59 fee. It's incredible!
4. The fundamentals haven't changed. Don't become whale food. If you sell, Larry Fink will get your Bitcoins. I bet they will shake out all the weak hands, and soon after, we'll see an impressive rally with the price hitting new all-time highs in no time.
If you find yourself in a situation where you need to sell BTC to pay bills, it means you didn't manage your risk properly and bought more than you should have. That's why studying is crucial. It's not enough to put all your assets into #Bitcoin and assume it will always go up. Corrections like this are normal; this wasn't the first and won't be the last. Learn to be prepared to take advantage of them, not be destroyed by them.
