they imagine a number and write a protocol for attributing units of that number to online addresses.
oh look who it is again.. trolling that bitcoin has no economics/function/utility and is just numbers
even when using AI to hide your normal whiting style, it still seems obvious your the same troll..
havnt you learned anything from the last several accounts you made to fail at basic economics
..
lets dumb it down for you, again
bitcoin doesnt just create numbers. it uses WORK (calculations that cost electric to perform a task that generates bitcoin as a reward for work(cost))
for security... people then trade that reward for money or use that reward for many things... speculating above the most cheapest work cost on the planet, because different people have different work costs to generate bitcoin so some people want to just buy instead of work for it. yep some lucky places can work for $20k/btc. while other island nations its more like $150k work cost to generate fresh bitcoin rewards.. so the market speculates in between value and premium
the reason why bitcoin is above $20k base value and market speculating at $35k.. vs an altcoin of similar PoW method that trades at $1.20.. is that the amount of WORK the altcoin at $1 puts in is 20,000-30,000 less work cost
bitcoin is not just a "unit generator" its purpose is to do many things. the work and reward is for securing the other features bitcoin does and people want to do things on bitcoin using it
there are some crapcoins that market speculate outside of their underlying security cost. even hyper speculate above the most world wide premium of security cost (most PoS coins)..
there are some tokens that dont even have proof of transfer, dont have secure auditing, dont have secure ownership proofs..
bitcoin are not like those PoS or token crap. bitcoin does have many features that make it useful, secure, provable
