If a good number of people adopt Bitcoin and agree that it's money then it can be self-fulfilling prophecy, but this should be based on real rational expectations, Bitcoin as a store of value, unit of account, and medium of exchange, not merely a speculative vehicle which would end up in a self-fulfilling irrational speculative equilibrium which isn't good.
Bitcoin is dualistic in nature, as a currency and a commodity, it is good and bad, speculators make it a too volatile medium of exchange, but for widespread adoption and putting an end to bubble theory, Bitcoin needs to get adopted as a currency. Merchant adoption is the key.
Brilliant comment! Thanks for that!
Question. Might it be accurate to say everything said in your quote above applied to gold and precious metals in previous eras when gold and silver were commonly utilized as both speculative vehicles and currencies? I'm far from being an expert on volatility and trading history of precious metals. Would not be surprised to learn there are interesting analogies which might be drawn between the crypto of today and the gold/silver of past ages.
Also in regard to crypto volatility, it is possible we might eventually reach a saturation point where enough relative unknowns in crypto are quantified or eliminated for volatility to decrease by a significant proportion. Being near to the early adoption phase leaves room for growing pains but there could be a future era where the technology matures enough for the wild price fluctuations to become minimalized.
