You're correct because dollar is a debt unit - an instrument of debtors liability created at a bank via loan contract. That's why you cannot create dollars here on the forum. However, bitcoin is just a dozen of binary digits. And those can be created everywhere by anyone.
you are not creating crypto currency on this forum
what you are not realising is money is created
within its own monetary systems
bitcoin is created within the bitcoin network via the bitcoin rules and bitcoin never comes out of the network
EG the EU banks create EU bank notes in the EU system.
people do not just create bitcoin/crypto currency by just sending a tweet or message on a discussion forum
it involved code and rules to actually have policy of control and rules of transfer within a monetary system.
if you dont know how monetary systems work. dont waste months thinking you can create money randomly .. instead actually learn where and what the money systems are and the mechanisms involved to create money in those systems
That's why you cannot create dollars here on the forum.
...
Thousands of crypto system as well. It's just that people give different names to those digits. Simply, whoever needs them digits can create them at an instant.
fiat is not just dollar.. there are hundreds of fiats. multiple different "dollars"
canadian, australian, sinagore, liberia
but they have their own systems
each crypto currency has its own network and system and policies too.. you do not create a crypto currency by just describing it on a forum
So, why are you people spending tons of energy or money to get them?
different monetary systems have different communities with different reasons or needs to access those systems. they offer different features, different benefits. and different value creation mechanisms
bitcoin offers a deflationary system to hedge against all the fiat inflationary systems
bitcoin has features for international reach that are better and cheaper than fiat remittance abilities and costs and time
the cost of creating new coins within bitcoins system offers long term benefits for that involvement. and the costs then support the underlying value.
for instance PoS coins have a lower cost of creation. meaning when the market speculats to their ATH there is alot of no-value bubble price difference compared to its underlying value amount.
ethereum right now has about a max value line of $50(compared to its $900 value line as pow) so it went to a 1.6x market speculation to a 24x market speculation when it swapped to PoS
bitcoins value line is abut $15k and its market was at a 5x speculation hype bubble when the ATH temporary event last year occured. and is now back to real good value of 1.1x
there is alot you need to learn about monetary systems. their money creation policies. their value discovery and underlying value support amounts. and the speculative markets above value
