The Halving of bitcoin might kill the Blockchain temporarily.

At the time halving is happening the price might rise causing a surge in transactions. As we are aware of the Blockchain currently running a 1 Mb per block, block size. However Bitcoin Classic with its 2 Mb block size might take over before that time. In any case the number of transactions might spike to a level we have not had to handle before and this will cause delays. Speculators might lose hope because of the delays and the block chains ability to handle the transactions amount. This will affect the price and it will fall dramatically. Miners will then lose revenue due to the reward being halved and prices might be low. This will cause the miners to poll out and the hash rate will fall. But the difficulty will remain to every 2016 blocks. In a worse case the difficulty has just change right before the speculators lose hope and start selling. This will accumulate to a long block time and may well over pass 10 minutes to solve. We might even see block times as high as hours. This might cause panic sales and the prices will fall even more causing more miners to pull out because of loss of revenue. The Blockchain will of course correct itself once passed the next difficulty level but this might take weeks, months even years.
