So segwit will supposedly be activated this Fall right? This should mean blocks are no longer near full, transaction fees go back down to hopefully 10 cents or so, and sending bitcoin will go back to taking tens of minutes instead of hours.
Right.
What will all this do to the price?
This will result to a tremendous increase on Bitcoin's price. Though I am uncertain of what will really happen, I am on the positive side. This will be a milestone for Bitcoin and investors will start pouring in. So there is no doubt about the Bitcoin price increase.
Will this first step in scaling be the sign investors need to really start jumping in on Bitcoin?
Yes.
Will it be the sign the USA SEC needs to approve the Bitcoin ETF, allowing people to invest in bitcoin more easily?
Yes also.
Assuming bitcoin growth slows down this summer, will segwit create another boom this Fall like we've had this Spring, sending bitcoin possibly close to $10,000 by end of year?
Whatcha think?
Bitcoin will definitely slow down before segwit. This is due to some people selling coins because they are afraid of its end result. However, after the activation, about a week or so, we will see the tremendous growth I was saying earlier. 10K is a bit much, though.
