The price grow so fast o think, it's even reach more than I expected, yes this year is a bitcoin shine but the problem is how bitcoin survive?
The big question will be, if we can scale quickly enough with the current code to accommodate for mainstream adoption. We have been fighting
about Block sizes and scaling solutions for most of 2016, and it is time for us to tackle this problem together. You can decide to scale
conservatively and in the process cause frustration with slow confirmations { if this goes mainstream } or you could scale aggressively and
then run the risk of opening new attack vectors.

To Big block or not, will become a forced decision at the rate we are going now.
That's the biggest dilemma for bitcoin nowadays, it's feels for me, especially the transaction goes to slow even have more time to confirmed (my experience over 1 hours, using default fees from my wallet), unless put more fees/any factors which to add more priority.
