Ever since bitcoin's early days most people didn't show appreciation. While acknowledgment of bitcoin has increased and demand has risen a lot, it's not necessary that those criticizing bitcoin were wrong.
We may not compare that time with this present dispensation, because things have already turned away from how it all started to this big, when bitcoin was at the early stage, it has no value and people don't even expect seeing it to have become this great, which was at as then, but in today's era, things have drastically changed and the those criticizing it are not having a broader idea about what bitcoin is, that is why we could still discover about some previous critics turning into bitcoin supporters now, after they learnt about their initial impression to be wrong.
What has bitcoin achieved recently? Getting in more exchanges, getting in ETFs and wider access to traditional markets? Sure. Mining becoming an industry? Ok, let's count that too. Does that mean bitcoin is being appreciated for its values of decentralization and immutability? Probably not.
Nothing is changing about bitcoin, but bitcoin is the one causing a lot of changes to everywhere, that is why they are now seeing the power of the bitcoin community, the influence of bitcoin enthusiast, the unity, security all that could benefit them with the use of bitcoin and its network to achieve financial and economy balance.
