No need to get panicked. The jump is due to new product test & release. If you look at previous charts there are many such jumps. BTC price will caught it. Be cool.
for sure the extra hashing power of the network is needed, in order the transactions to be confirmed in minimum time.
Check now when you make a transaction then in about 10 seconds its been seen by 3-5peers.
this helps but has to be stable.
Gradually the money we all miners put in the bitcoin is expanding the bitcoin in general.
But there has to be a limit so other people and not only miners adopt the bitcoin.
these spikes in hashing will gradually reach the customers after a week or so shipping
I hope that the new miners ROI without the price increase and if it happens its a good thing if not
remember the 300 usd this earlier year.
Anyway fingers crossed now.
