Bitcoin will still exceed it's 2017 high. I do not have any data to support this belief, but bitcoin has continued to defy the odds. I strongly believe that it may even get to $50k one of these days. $0 to $21k was not on anyone's radar yet it happened. $21k to $50k can readily be achieved.
Bitcoin has surpassed everything we could have imagined and every single prediction that we could have made, at the very same time it is difficult to think that bitcoin is going to reach such a high price in such a short amount of time especially when people are afraid to invest in cryptocurrencies after the crash.
Yeah, for one fact that even when a lot of people saw $10 as too much of a value back in those days, tells us something that we may not actually have hit it yet and based on the fact that we are even still in the early days of adoption shows we are not even close to the peak at all.
I am very optimistic and bullish in the long term on bitcoin and that is how it is going to stay until we finally hit the mainstream and adoption for usage as currency. For next several decades of years, no one can be sure about the peak price levels of bitcoins as bitcoin's demand may keep increasing along with its popularity hence price must keep increasing in coming years. Peaks may be found near to billion dollars too.
