If I needed fiat currency.

but the sad truth is that we dont know about the future. if i know it too, i would do the same thing too.

Am at my last breath

Yeah future is uncertain and we don't know what bitcoin holds us for the future, but selling all your bitcoins would be silly thing to do, as you cannot afford to sell all your bitcoins at a single moment, it is better to sell part of bitcoins and earn profits and keep rest for the future and if the price falls down you can still afford to buy more bitcoins and wait for the price hike and that is the best way to deal with bitcoins.

I would sell all my bitcoins if the price skyrockets to $1500 overnight or I double what I paid for them!

I would sell all my bitcoin if i have many bitcoin in my wallet, because i don't have any lol. and if bitcoin price gonna high again i will sell .

I would sell mine under a few conditions. The main one being if the price was so good that I couldn't pass it up. By that I mean prices to the point where I could be set for life, doubt it will get there in my life time.

I still wouldn't sell all of them though. I would still keep a stash of them in my wallet just because.

I agree with that, however i do not see it reaching that high.  Maybe close, around 1,600 or so, which then it still would be worth selling, but I see no reason or facts behind why it would raise that high, unless there was a large demand for using it to pay for something specific.

I would sell all my Bitcoins if i would find any good macbook at the cheapest price possible.
Otherwise i will hold for a long time maybe until it reaches the target of $1,000 for each bitcoin.
