Let me even use you as an example, you already have like 10btc in your wallet which you had few years ago. Knowing its worth now, would you want bitcoin dead?
No, of course I don't want that, but at the same time I prefer to hold my coins rather than spend them.
When I say it's gonna die, I mean that Bitcoin is becoming worthless as a payment service, not as an asset.
Oh ok! I understand your point of view now. The funny thing is people will still keep exchanging irrespective of the exchange fees, speed or whatever and you know if it becomes worthless as a payment service, people will start dropping it and definitely it becomes worthless too as an asset. There are two categories of people thay keeps the system moving, THE HOARDERS AND THE SPENDERS and without the two, it is a NO NO. What is increasing the value today is how readily people are accepting it, using it to pay for stuffs and exchanging it.
Demand and Supply - that is what adds value to things anyway even fiat currencies. Once there is always more demand and less supply, the value rises and the two must always go hand in hand. So once it starts losing its value, it gradually starts getting worthless, and people may start looking for a better alternative if there is any.
And since you already said you prefer to hold your coins rather than spend them, you won't as well want the value to drop right? I am sure no matter how bad the payment service is, which I don't really think it is considering the value, exchange won't stop. This is just a little I know about how the exchange market works though, maybe the gurus can shed more light.
