There was a time that bitcoin plummeted to $6,000 and those who have bought with that price can retrieve their profit regardless of the corrections right now.
Exactly because that was the dip during those times, well maybe last year it was $3k but from that price bitcoin have pump a lot reaching to $13,000 then it falls back to $6k then pump again to $10,000, then fall back to $7000 by the end of the year.
This year we reach $9000 by the end of January and if people are just playing games with the volatility, they can make profits many times since many times there's an opportunity given to us traders.
