... payment protocol and money function at its starting price of 0.001 $?
many people thought what you thought. they made their forks and are playing with them now.
but what you dont realise is this
1. the price is made up by the acquisition costs (costs of getting it) when a mining pools needs to buy equipment and pay electric of $5800 to mine an amount that equates to 1btc. he wont sell for less.
the person he sells to might squeeze the pools to sell for $5801.
the person he sells to might squeeze the pools to sell for $5802.
and so on (usually people sell for more that 0.x% profit)
what you find is over time the price goes up because people want it. they see it has purpose. there are merchants. there are goods services that can be bought with it. and ofcourse because of costs they know they can get a certain amount back when they sell it if they dont spend it on goods or services.
those silly altcoin forks that people made and are playing with because they have the mindset of why use bitcoin when they can take the protocol and start their own.. do not have the awareness and acceptance from merchants and those selling goods and services. and do not have a mass of mining hardware to protect their silly altcoins.
if you did not realise. if it costs $5800 today to mine 1btc.
thats made up of a math of it needing X miners a day to make 1800btc
now for an attacker to try to edit the blockchain from the previous block requires X miners to get the data from 2 blocks ago. edit the previous block but include the header of 2blocks ago. create the block solution of the previous block and then mine the another block to even out and then another block to over take everyone elses version.
so knowing it will cost alot to do this it becomes not worth editing the previous block to reverse a transaction you mad to buy a coffee. because it costs 1800x5800 to edit just 1 previous block
now to get the speed to edit a block a few blocks ago. you need to harness even more mining hash speed. so thats even more hashpower then the network if you want to edit mine and overtake to lock in your edit. so it costs you more.
the further back you want to edit the more its going to cost you.
this is why people are happy with bitcoin because its costs more to edit out a transaction than a transaction is worth. and the more difficult it gets to mine a coin the more protected the transactions are
so if you see a coin for pennies. you will realise it only costs pennies to protect it which means someone can copy and overtake cheaply
