But how does the two differ? Regardless if the price has pumped and the sell/buy orders don't have walls at all, the "virtual" price of bitcoin is the actual price of bitcoin. There's no other way to determine the actual price of bitcoin but to look at the virtual price that you're saying. Regardless of how it was built, it's the price.
Too much volatility is kind of risky so you should always watch the charts. The good thing, though, the volatility itself made the price of bitcoin increase to this point. It's what made us get profit although it can also be the reason why we lose money. It's a double-edged sword.
