Still the main use of gold is for jewelry, and it's questionable whether gold will be in demand in this industry in the future.
And I disagree on "only speculating or hold".
Many of us here, including you, receive payments in BTC. Receiving payments in fiat currencies would be much more complicated.I didn't deny it.
Yes, the main use is for the jewelry market (for about 60% actually) and it's not going to change contrarily to what you think. The demand will be the same, more or less. We're using gold for the jewelry before Ancient Egypt, 3000 years ago before Jesus Christ.
Why and how will it change in the future (near or not)
on "only speculating or hold"
Yes, some people (including me) receive payments in BTC, well what I call real uses cases. But face the reality, the percentage of people using BTC for something else than 'real use 'case' (and here I mean only speculating) is the vast majority.
70% of the transactions on the bitcoin network are related to trading activity. I could link the research if you don't want to believe me.
Not even a need for research to guess it, we perfectly know the crypto sphere, it's just a matter to accept the reality
