I believe that 2018 is a turbulent year for BTC. The sudden increase in sales prices this year (January) surprised many people. I believe this is a stepping stone for the development of electronic money. All you need is patience and expectation that is the key to success in the field of electronic money.
I agree with your opinion. At that time I was very surprised that the price of the BTC increased so suddenly. Because of that I have sold out and made more profit. Its price has fluctuated in recent months, I just hope that in the next few years BTC will be less volatile to attract more investment.
