As a bitcoin user I'm sure I'll be optimistic about price increases every year. Not all digital assets are always up, some even do not develop and some are dead. My reason for bitcoin will still go up is because the number is small and the demand is still a lot, then bitcoin will always be above than others. Now bitcoin also enlarges networks in different countries. So the probability is bitcoin will go up. I also can not predict when bitcoin price will be at the top.
