You summarized what is important to note about Bitcoin as a currency and as an asset that's good for investment.
Bitcoin has proven to be a safe haven asset since meeting the requirements and after the launch and approval of the spot exchange traded fund, that's the spot ETF, because without the ETF approval, it would have not been possible for large pocket investors like big corporations and businesses with large capital to invest in Bitcoin as an asset of value and am sure also if Bitcoin did not have the potential and prospects of increasing in value and returns, regulatory agencies, that's the SEC, would have not allowed its activities and use to be regulated citing it as irrelevant or a sham that has failed already with proofs of such failure.
We've seen how the value of Bitcoin went since the day of it's creation till this point anf though it's volatile in nature, it still has the potential of retracing to different ATH whenever it's price goes down which makes it a good asset class and one of the best to invest on especially for long term investment and knowing that the ETF was approved for more big investors, industries and companies to come in shows that it's a very valuable asset to invest on if Bitcoin was worthless then I don't think there would be any need for ETF approval or arrivals on big investors. Bitcoin is a very good asset for investment but then I'll still continue to advise that one must be very knowledgeable and understand it properly before making any investment whether long or short-term.
