Things can easily snowball out of control and likely will - people buying before the halving will be reported by the media and the publicity will lead more people to buy.... Then the halving of surplus coins will take effect so there will be a new ALT.... and it might even shock us all come before the halving because people I have talked to are stocking up in advance
like the Gox bubble?
I hope because bubbles are lucrative and some people always stay when the bubble poops
The next bubble might be driven by users rather than artificially trading bot or gox cooking the books... But literally anything could start it, maybe we'll see it well before the halving
Even 1 single country dumping funds into btc could have a huge effect on the price
