I think that in April, the pump will be still moderated. We'll have to wait until the end of May or the beggining of June to see the price reach 600$.
I think it will be before that probably. Maybe even the beginning of April when we start to see a pretty high spike in price. I think at first it will spike off into the area around $550, stagnate, then boom to about ~$800 with upwards momentum when we pass the halving. All in all, after we pass that point, we will start seeing some major resistance around there... You have to think, there is probably a lot of people who have been holding their bitcoins who got in during the 2013 bubble and just want to end up breaking even in their investment. So once I think we get close, you will see a lot of people selling out because of the powers of FUD.
Maybe your prediction will be more true than mine, and I don't except it
. You say a lot of people will sell, to have their investment back, the price will have to go really high. Also, if you're right, this mean that the price will fall after the halving ? To which point to you think it will sink ?
