Shoots up to what price? 1000$ or 10000$? I am planning hold unless I really have to sell to fulfill some emergencies.
It really depends on whether there is a financial collapse or not. If there is a financial collapse worldwide then I think that it is a good idea to hold personally because as soon as you convert your BTC into fiat you are losing value, fast.
That's not a great idea, but if it is just pure speculation and bulldozers drive the markets up to $10k then i think it is a good time to sell.
