I think this is the wrong view. Market ups and downs are very normal. Bitcoin will land when it takes off, so there is no big prize, but it won't disappear.
in my opinion this is a wrong view of bitcoin. bitcoin won't end at any time. if bitcoin will be lost maybe other coins will be affected in investing.
I think many people are focusing on the aspect of "bitcoin may disappear but for that to happen something better must come" but they are forgetting one key thing. Bitcoin is already something new, it is not a 100 year old thing, its just 10 years (not even) since it came out, gold has been around forever, dollar has been valuable since 60's and definitely since 80's as well, here we have bitcoin that came out almost 10 years ago and you are thinking about something that could overthrown it.
It won't happen easily I can tell you that, whatever comes up that will overthrown bitcoin must be out there for a long time and needs to take its sweet time before it can even reach to its levels, it won't happen overnight at all. Considering all of this we can safely sleep at nights knowing bitcoin will be here for a long time.
I think it is totally nonsense. If somebody has a problem with bitcoin or cryptocurrency he should not put his money in it and quit this world forever. With the passage of time he would understand the importance of bitcoin and then may the price be more than $30000 and not able to buy even satoshi. I believe bitcoin the most and think that bitcoin is the future currency.
