If history is any indication, then the halving will first commence.

An interesting question. The halving is one thing that does seem to be agreed upon so that's likely to be first. I'd be happier and feel more positive if it was vice versa but that's life.

The halving will probably come first, but that doesn't mean we won't have a capacity increase. SegWit is supposed to come out in April, which is two months before the halving. SegWit will bring with it some capacity increase.

We need "consensus" for the block size debate to be resolved. I wouldn't put my money on that happening any time soon.
So I would go for halving.

the roadmap is telling me that the segwit thign will be implemented in april, so i say the block size, unless i'm missing something

if you mean the normal increase to 2mb, this is not going to happen in any case already

Block size increase will happen after the halving. Because the the debate is ongoing for many months and there is no quick solution at the moment. But halving is planned on the timetable.

I din't think that the problem of block size will be resolved so easy. The main core developer (Gavin Andresen) it is supporter of "another" bitcoin. With him even another charismatic developer as Jeff Garzik. The others remaining at bitcoincore are unknown people and with less contributes in the actual bitcoin (as it is actually). I don't see any point in which these two groups can be together. Every each of those has already its bitcoin and is working for it. So, according to me, not only before halving but even to much time after halving there it will not be a solution of this problem. Being not a technician (devs or programmer) cannot be able to tell if this division (if can be successful both variants of bitcoin) could affect the halving but normally not. It would be the the halving of the bitcoin of today and not of the bitcoin classic. Anyhow if both are bitcoin and have the same code and development (except the block size) can (or must) be even the halving of the other one. Anyhow this is not something that is much important for this thread so have no meaning to be analyzed more.

What I hope : 1 - Block size issue getting solved to end the nonsense drama. 2 - Block halving.

What I think will happen : 1 - Block halving. 2 - Block size issue being solved.

If the block size issue is getting solved first, then we can have a real HARD pump when we go towards the block halving.

For that I can understand it is the second one contributor on the development of the Bitcoin Core if it is taken as a point of reference this website:

And in which I found the below data:



Anyhow, as I told in my post I am not an expert in such field and here the numbers cannot have that importance given or taken by me. But for sure I know another fact which cannot be never bypassed by no one. Gavin Andresen was the only person to whom Satoshi gave the codes of bitcoin and if so must be the most professionally able and prepared person in this field according to the inventor of bitcoin. Otherwise have no sense that was the chosen and the only One who has the trust from Satoshi.

and wladimir seems the first and he is still working on core, so i'm with this guy than anyone else on the team there
