As we see the bitcoin value is gradually decreasing again on this moment which is from 8k the price fluctuate back to $7900 , now we need strong explaination about this which is if it's a normal correction of price or it will decrease gradually again back to the bottom. ?
Wrong. The price isn't "gradually decreasing". And what we're seeing right now isn't a correction, is just normal fluctuation, and no, this minor decrease in the price won't take us back to the bottom. To be honest, even worth discussing about a -1% change in the price in the last 24h isn't even worth discussing about. If you're one of those who gets worried about such insignificant changes in the price, then I'd recommend you to stop looking at the charts so often.
