The coding system behind Bitcoin makes it impossible to counterfeit

Question: Is Bitcoin the future?
Position1 of 2›: Yes, Bitcoin is the future
Argument‹5 of 5: The coding system behind Bitcoin makes it impossible to counterfeit

The block chain technology Bitcoin runs on includes protections that make it so that the cryptocurrency cannot be counterfeited. If someone attempts to use Bitcoin more than once, the system will block it.

The argument

The block chain is the skeleton of Bitcoin, a digital ledger that regulates and tracks the owner of every Bitcoin and every transaction. The block chain is how Bitcoin can be decentralized unlike a traditional bank. When a transaction occurs or a Bitcoin is mined, the device adds on a digital “block” to the chain, which details the transactions sender, receiver, and amount. Thus, Bitcoin’s information is distributed to those using it, each adding a block onto the chain which tracks the entire Bitcoin economy. If someone were to spend a Bitcoin more than once and counterfeit it, the chain would branch. Two (or more) blocks would be added containing details for the same Bitcoin, so the blocks would exist side by side as two branches in the block chain. The block chain and the computers running Bitcoin protect against this. In instances of branching, Bitcoin accepts the branch which has spent the longest time as part of the block chain. The “real” (or first) transaction would have the entire block chain attached to it, while the second would be a brand new one. The longer branch would be accepted, and the software would treat the counterfeit as if it had never occurred. The only theoretical way for a Bitcoin to be counterfeited would be for another branch to surpass the length of the original. However, this would require a counterfeiter to control a large majority of the CPU power of the entire Bitcoin network, meaning one user would have to have a power equal to millions of computers. This is practically impossible.

Context

A major reason many people are distrustful of Bitcoin is for fear that since it is entirely online, it could be easily counterfeited.

Premises

[P1]The blockchain is a decentralised digital ledger in which every transaction adds a 'block' recording sender, receiver, and amount, distributed across all users so no central bank is needed. [P2] If someone tried to double-spend, the chain would branch, and the network always accepts the longer branch, treating the shorter counterfeit as if it never happened. [P3] Overtaking the real branch would require controlling a majority of the network's CPU power—the equivalent of millions of computers—which is practically impossible. [C] Because its coding system makes counterfeiting practically impossible, Bitcoin is the future.

Counter-arguments

It is likely somebody will figure out how to counterfeit Bitcoin. Despite numerous government protections, people have figured out how to counterfeit government-backed currencies, including national bank notes and Federal Reserve notes, so they will be able to figure out a way to counterfeit Bitcoin too.

Rejecting the premises

[Rejecting P1] Blockchain technology is not foolproof. [Rejecting P2] Blockchain technology makes counterfeiting incredibly difficult, but no system is impossible to hack. [Rejecting P3] Many secure types of currencies have been counterfeited before. Therefore, Bitcoin will eventually be able to be counterfeited as well.
