As a trader, I never expect bitcoin to go only up because it happens it will get hard for me to make significant profits. I buy when the market dips and sell when the price is at its peak.
The ups and downs of the bitcoin price are normal for a trader, but nowadays there are many new investors who want to use bitcoin only for their profit and wealth, when the Bitcoin price goes up they flock to buy it, when it goes down they don't accept it and think it's a scam,
Research on Bitcoin and crypto is important before starting to enter the market.
