Beginning of this year I see BTC and altcoins markets are higher valued. But Since Feb of this year thats markets are falling down. Its still not yet stable and i see lot of Panic seller in this period. I want to know whats the reason for it. Please give any idea 
If we are talking about the price of bitcoin as a whole, then this is a common correction, you are a person and you breathe air, the market is also breathing, it can not constantly breathe in and increase, the market definitely needs to exhale.
