How is the current price of $9000 a dump? We were only at around $6000 a month ago from now. We just recently peaked at about $11,500 just days ago. A price correction was very expected. Do you really expect a certain cryptocurrency, stock, or asset in general to go up forever?
Sell now and buy 2, 3, 4, 5 times as many coins when its cheaper
The question is, will it go cheaper than it's current price? Nothing is guaranteed.
That is the problem with people when the price goes down for more than a thousand they will panic and say that there is a dump happening, they don't realize how fast the bitcoin reach that amount. Trading stocks are gaining an average of 12%-30% per YEAR and bitcoin gained more than 900% in less than a year so how can we say that the price is already dumping where in fact it never went back to it's price a year ago.
Most people are seeing bitcoin just as an investment and whenever the price is going down instead of hodling the coins and wait until the price recovers they would rather sell it to cut their losses, because of this practice bitcoin's price is getting too unstable. Just trust Bitcoin and see what will happen.
