How would you define the collapse of Bitcoin? Do you mean it ceases to exist or are you defining it by a certain percentage drop in price and if so what is your target that would qualify in your mind as "The Collapse"?
Anybody who bought in in the last 3 months only seen a bullmarket and BTC going up. Finally in the last 3 days it is dropping, and if you bought in at 15K, 13.5K doesn't look that great. Now if they actually know BTC's history, they might know that it could drop even more and it might need another year just to get back to breakeven. Late comers always end up holding the bag...
In other news: The Bulgarian government are denying they have 213,000 bitcoins. They just disappeared!
