But if compare all three, bitcoin is the market is most similar to a zero-sum game because the value of bitcoin is based on its expectation and scarcity. The investor's profit comes from other people paying higher prices. Unlike stocks, profits come from the intrinsic value of the company, stock prices increase due to the growth of technology and the company.
The Bitcoin market needs to be adopted more widely, needs to be applied more practically in life, instead of just being used for speculation. Only then is it truly a positive-sum like stocks. But in the short run, it's all a zero-sum.
I do not know how someone judges zero-sum based on their respective perceptions but in the context of knowledge that I know, it is nothing more than someone who gets profit and one other person suffers losses.
If it is related to Bitcoin, I see zero-sum unfit for being embedded because when the seller gets a profit and who buys to get assets, and vice versa when the buyer returns to sell when the price increases he also gets profits.
Bitcoin is more ideal to be applied as a long -term investment based on some of its advantages.
People's perspective may be different and I believe it is based on what we know because no one has lost when investing in Bitcoin, unless they make mistakes and are panicked when Bitcoin has decreased.
