You shouldn't be selling your Bitcoin AT ALL, and acquiring as much as possible, you want to know why?
Because if there is a Hard Fork and a new Blockchain is created with Segwit activation, you will end up with FREE SEGWIT BTC. That's right, you will still have your Bitcoins PLUS the new Segwit coins on the new blockchain. If you have 10 BTC, you will have 10 BTC + 10 Segwit BTC. So if you were smart you would be acquiring as much Bitcoin as possible, especially while it is cheap, before the Hard fork.
That is my opinion.
You're a Legendary and this is what you write without properly explaining or mentioning value - disgusting times we live in.
You are just a speculator plain and simple, and BTC would be much better off without idiots like you.
Everyone is a speculator when it comes to Bitcoin.
