This is not the end of Bitcoin. It is was just manipulation. Bitcoin will be back again to it's previous position again very soon. Maybe it will be happen after Bitcoin reach it's bottom price.
Bitcoin prices go down is a reality, not manipulation. Bitcoin holders don't need to panic, because this part of the bitcoin cycle has a time of high prices and sometimes low prices. It must be optimistic that bitcoin will pass all of this to return to being the most sought-after coin by cryptocurrency lovers. If someone says this is the end of bitcoin, then they don't understand the characteristics of bitcoin, and maybe they don't like bitcoin.
