If stocks go down by more than 2%, everyone thinks that it is a crash and that everything will collapse, i am telling you this because i have a huge amount of money invested on stocks.
If bitcoin goes down by 10%, no one cares

Recently Bitcoin got very high fluctuations. It went up 19,000USD(nearly) and dip to 12,500USD. In this situation does BTC stable ?
What are reason for that kind fluctuations ?
How long it will take reach 19,000 USD with this kind of market fluctuations ?
Any financial market has volatility, that is, it fluctuates and this is normal. As practice shows, bitcoin has fallen more than once, but then it has recovered with a margin)
