Because holding doesn't make much sense
Especially, if we are talking about an asset which has no intrinsic value of its own and could easily lose all its speculative worthiness which it has right now. I don't mean today or tomorrow, I'm trying to look further into the future. Could Bitcoin price remain the same over, say, a ten-year time span? As I see it, this is hardly possible. It is basically neck or nothing in the long run for Bitcoin, either win or get nowhere. Indeed, some people may want to hold till the end, but it simply doesn't make sense in the latter case
Bitcoin is the biggest decentralised open-source and most secure computational and financial network.
How can you possibly say that it has no intrinsic value?
Alone the infrastructure (i.e. asics) are worth hundreds of millions $.
Bitcoin is 7 years old now and we are still at the beginning of the adoption curve (much less then 10 million user).
The reason is that people want to be independent and bitcoin gives them the power to be so
Beauty is in the eye of the beholder
If Bitcoin lost a utility for speculation (as well as transactional utility as a currency, however small it might be), it would be worthless despite all the millions invested in mining equipment. When railroads quickly evolved in the 19th century, inland navigation declined as fast, and all those expensive ships and boats became mostly worthless. So how can this utility or value be possibly called intrinsic at all if it can be taken away so easily?
Btw. Correct would be: most of the time. Learn some grammar!
Google is your friend indeed, but you still don't have a clue what you are talking about. Most of time basically means almost always (just what you actually meant to say, though incorrectly), while most of the time refers to a specific period of time which should be understood from the context. Below is a real example from which you may try to comprehend the difference (you can also do some google-fu, there are plenty of such examples out there):
It’s not about you talking most of time [i.e. always talking] but it’s about you listening the most of the time[i.e. listening when you are being talked to]
If you still fail to get it, the difference is essentially the same as between most people (i.e. people collectively) and most of the people (i.e. a specific group of people). Thus, instead of claiming that you know 30 languages, you'd better master at least one
