... the price fall is more than the rise
WRONG.
you need to look at the bigger picture.
right now you are just looking at a short period of time where bitcoin price has came down a little. if you look at a couple of months you can see a rise from ~$880 to $2900 and right now it is sitting between $2200-$2400.
even if it falls more it will still be much much higher than the couple of months ago.
with that said, did you get your answer to why people hold bitcoin
I agree with BrewMaster. In situations like this, it is important to consider the bigger picture which could symbolize the long term effects rather than the subject of the picture alone or what depicts to be the short term effects of the Bitcoin downfall. We should all remember that Bitcoin is highly volatile and with that being said, anything can happen in a short span of time; but always know that these changes are temporary. Just like what BrewMaster said, Bitcoin will fall in greater heights but it will surely rise to a higher rate that it may exceed our expectations. This is why people hold on to their Bitcoins despite the thought of its continual decrease, when Bitcoin recovers it exemplary recovers. It is worth the patience of holding on rather than just selling it.
