I believe the price has come back to normal and that sharp growth was just temporary. As a matter of fact, bitcoin is always in fluctuated movements. Most of the time, when it increases or decreases, it always remains in that level for a long period and then go back to what it was before.
The best option here it to be patient because bitcoin is all about patience and commitment. If you are impatient, then you will lose too much profits and regret it. You also should believe in bitcoin because I am sure it will go up again in a matter of short time.
Honestly bitcoin is not going back if what it was before since bitcoin was increased a lot from november to december the same as what movement happen in the past year so if what the price happen today i think its normal that we are seen the price was drop that is why there are trading site..
The purposes of trading is to buy low and sell to get profit what you invest..
And i think this is not the end of bitcoin expect that the price will recover slowly just like what happen in the past years ago..
If you can't hold your bitcoin you will lose if you bought them in higher price.
So to prevent losing your investment better to wait for the price of bitcoin to recover but i feel that it takes a long time again to see the price is above $10k..
