By then then the fees hopefully make it profitable through it. But that is SO far off we cannot really speculate. Even speculating what will happen at having is hard to do at this point.
I keep hoping to see a value bump in BTC but it's been a lot slower then I had hoped. I don't see having as a big day on value jump as we know it's coming. So I think it's more slower process.
Yes, I haven't found anyone yet among "the knowledgeable" who are willing to stick their necks out and issue a learned prediction on where things will stand in two months.
And then after that, I suppose that we'll all be watching to see what happens in Spring 2017 when the core group will be able to finally sell off their huge BTC holdings, if they so choose?
It looks like an interesting 12 months...
