Long story short
Bitcoin isn't an asset that should be traded.
This is an interesting perspective you brought out, i guess this is one of the wrong mindset most newbies put into there minds when learning about BITCOIN well as we all know BITCOIN investment is know for a highly volatile and most speculative investment we all know that BITCOIN can be considered a unique asset and unpredictable assets it can be used for store of value and speculation which mean buying BITCOIN for the future used.
Because even though Bitcoin is already accepted by most companies for payment, it doesn't mean we should use Bitcoin to pay for something that is not much more valuable than Bitcoin. So that's why some people say that Bitcoin is not an asset to be traded even though Bitcoin is already on many exchanges at this time.
. The moment Bitcoin becomes accepted by lots of organizations, then we could see it in virtually all sectors of the economy including aviation, shipping lines, grocery stores and even the remote markets of Africa like the Kenyan Mpesa.
when we consider that some companies don't make use of bitcoin as an official payment option, we ought to ask ourselves the reason why that is the case. of the many reasons some companies might not have adopted bitcoin as one of her payment options will likely be that they are not a bitcoin enthusiast and also that the population of users of bitcoin that patronize them are not much.
if an aviation company for instance sees customers that week after week is willing to pay for their flight ticket in bitcoin, it won't take time before they include bitcoin as one of the payment options. but then, since it's a business that runs weekly logistic that involves spending regularly, the consideration on the volatility of bitcoin will then come into play which can stop some of them from taking the risk due to the fear that in times when the market is down, they might experience some loss. we have to note that even though at the start, the narrative towards bitcoin was more about using it for regular transaction, at the moment, such usage might not be all that effective.
It seems you have the very essence rof Bitcoin wrongly because Bitcoin was actually created to serve as a currency just like every other fiat that we have out there but its uniqueness is that it is not centralized and therefore not controlled by any single entity. Therefore, Bitcoin ought to be used to pay for goods and services, traded and allowed to stand as a medium of exchange. So the other part of your statement is wrong and not in agreement with Satoshi's vision.
theoretically, that seems really cool but in reality, what serves well for regular trades are stable coin that are almost of same depreciating value as the things you are exchanging it for. of cause, bitcoin was never created as a complete replacement of the fiat, it can still work side by side with the fiat such that for basic transaction and trading, the stable fiat comes into place while it serves for internation transaction and serves for saving purpose due to its potential of yielding returns in the long run.
if your fiat was not subject to depreciation and holding it can give you at least a 50% return on investment over a period of time, would you rather spend it than keeping it for the return you intend getting? bitcoin has grown above just an ordinary medium of exchange; it stands as one of the greatest or rather the greatest digital asset with the highest potential of returns on investment.
the decision is at the end of the day yours to make whether you want to spend your bitcoin on regular transaction and allow your fiat that is constantly being affected by inflation remain.
