If the bitcoin price goes to $5000 soon, say in a year, that is a big bubble. I will sell all my bitcoins.
Such a price is not going to happen. At the moment we aren't even at 10% of it. So no it is not something to consider however with any rise above the 1k I will join you to sell some of my coins. Never all since i believe there is so much potential.
The fact that it's just 10% of the target right now does not mean it won't reach the target in a year. Learn some Bitcoin history before you open your mouth.
