Currency Comparison: Bitcoin vs Dollar

By xuanling11 | Crypto Learning | 26 Aug 2021

This article may show you something that you may have already known, but I want to show you the different aspects of Bitcoin and the US Dollar. Which one is a better currency? 

The answer is that it depends.

Bitcoin is a decentralized currency using a peer-to-peer network called Proof-of-Work consensus without a need for third parties to process the transaction.

The US dollar is a centralized currency that the central bank oversees and facilitates transactions through a trust system.

Both currencies have their own method to prevent double-spending.

Bitcoin through cryptographic technology of unique digital signature and mining verification process while the dollar system uses the bank as a third party to verify the account integrity and to reject bad checks.

There are many other metrics that I want to share with you.

Comparison Metrics:

I will show you the metrics to compare these two currencies through the following factors:

- Total in circulation

- Market capitalization

- Divisibility 

- Hard fork

- Transaction speed

- Transaction cost

- Layer 2 solution

- Price volatility 

- Energy consumption

- Illegal spending

- Inflation/deflation

Total in circulation

It is how much money that exists in the system.


Bitcoin: 18.8 million 

US Dollar: 2.19 trillion 


Market capitalization

It is how much the total worth of market value is in the system.


Bitcoin: 0.92 trillion

US Dollar: 2.19 trillion



It is what is the smallest amount of money it can be traded with.


Bitcoin: 0.00000001 or 1 satoshi

US Dollar: 0.01


At current rate: 1 satoshi = USD $0.00049


Hard fork

The hard fork is when code changes so much that it is no longer backward-compatible with earlier blocks. 


Bitcoin: hard fork to Bitcoin cash 

US Dollar: hard fork to detach from Gold pegged currency after 1971


Transaction speed

It is how fast transactions can be made.


Bitcoin: 60 minutes or faster 

US Dollar: immediately if pay in cash but 1 - 2 days for the check

Transaction cost

It is how much it costs to process the transaction.


Bitcoin: $2.79 per transaction 

US Dollar: 0 per transaction using cash

Layer 2 solution

It is a scaling solution that is additional to the established protocol to help process transactions.


Bitcoin: Lightning network 

US Dollar: credit card payment system


While the lightning network in Bitcoin reduces transaction fees, the credit card payment system increases dollar pays. Especially the payment between international, the dollar system charged up to 3% of each payment transaction.


Price volatility

It is how each currency fluctuates each day.


Bitcoin: volatile

US Dollar: stable


Bitcoin is notorious for its fluctuating price that was marked as risky and it gained a reputation as security rather than currency. While the dollar is stable, other currencies may fluctuate largely. For instance, the Zimbabwe dollar shoots up 250,000,000% in July 2008.


Energy consumption

It is how much energy is consumed per transaction of the currency.


Bitcoin: 1 BTC per 1,722.24 kilowatt-hours

US Dollar: nearly zero


1 kilowatt-hour means a light bulb of 100-watt operating 10 hours.


Illegal spending

It is how much money is involved in illegal activities.


Bitcoin: $10 Billion

US Dollar: $100 Billion



It is how each currency may hedge against inflation or deflation.


Bitcoin: Inflation and Deflation

US Dollar: Deflation


Inflation means supply exceeds demand. The dollar devalued because it issued too much and exceeded what society needed. 

Deflation is when demand exceeds supply. It causes a decline in the price of goods and services.

Bitcoin price will rise in the long term simply because it capped the supply and Bitcoin can be divisible more flexible than dollars as a smaller unit to use. The dollar does not have a fixed supply and it is fixed only with 100s. 

The dollar will continue to devalue while Bitcoin will continue to rise.


Here is the summary table to conclude the above discussion


In conclusion


There you go. Which system do you like the most?

Hint: starts with B***
