Bitcoin economics has not changed

YOU DON'T HAVE TO BUY A WHOLE BTC BITCOIN! Each bitcoin is equal to 100 million Satoshis, making a Satoshi the smallest unit of bitcoin currently recorded on the blockchain. Think of the Satoshi as the “cents” part of bitcoin. But unlike a penny that represents 0.01 USD, Satoshi represents roughly 0.00000001 BTC — or bitcoin to its eighth decimal.

Bitcoin forecast to 2029

Time model tends to forecast lower bound to prices. Stock-to-Flow model is a better model, click chart above to see details. It incorporates the halvings and better represents the monetary policy of Bitcoin. Hype cycles are expected around each halving as investors anticipate the price appreciation. Bitcoin has a fixed supply (maximum 21 million Bitcoins), therefore it cannot be devalued by central bank money printing (so called Quantitative Easing, QE). Bitcoin is also decentralised, meaning no single authority can control it. It has existed on the Internet for 10 years from 2009. It will be the money of the machines and Internet. Also described as digital gold due to its scarcity and high value.

This is a good short article that explains, why Bitcoin? Why Bitcoin?

Be Your Own Bank
Bitcoin (BTC) is the people's money, owned by the people for the people. Not by a bank or country. What are you waiting for?

It gives you control of your money (individual sovereignty). Preserve your savings; they will increase in value over time. Easily send money anywhere. Government's can't take it! What are you waiting for? Get a free Bitcoin wallet today or, run your own full node.

Run your own Full Node and help the Bitcoin (BTC) network. Be Your Own Bank! There are currently (May 2018) about 138,000 full nodes globally. About 10,000 of these are listening for outside connections on the P2P network.

As people suddenly realise they don’t own their data on Facebook, how will they react when they realise they don't own the money in their bank accounts either?

The good news is government can't take your Bitcoin in your own full node. Not by legalised theft (inflation), nor by government bail ins. Realise that fiat money, $, €, ¥, £, yuan, Venezuelan Bolívar, Argentine Peso, Zimbabwean Dollar, etc. is crashing! In the last 100 years, all fiat currencies have lost 97-99% of their purchasing power, reducing your standard of living.

Physical Gold


Protect yourself and family from central bank currency debasement and inflation in asset prices, housing, food. There are rising levels of financial, economic and geopolitical risk in the world. In the last 100 years, all currencies have lost 97-99% of their purchasing power. Some believe that the final move to zero will take place in the next few years.

Currency debasement through money printing is the destruction of fiat money purchasing power - $, €, ¥, £, yuan, Venezuelan Bolívar, Argentine Peso, Zimbabwean Dollar...

True inflation and cost of living is currently 8% higher than the government reports. Real wages are falling rapidly and most people are taking out more and more debt to make ends meet. Only the wealthy minority and banks benefit from the current system.

Protect yourself. Buy physical, allocated gold, silver, platinum online and store it in safe vaults outside your jurisdiction (Switzerland, UK, USA, Canada and Singapore) or, at home. Physical gold has limited supply. Buy before the panic!

Look what happened in Cyprus (2013), Greece (2015) and Spain (Catalonia 2017). The lesson is that the money in your bank account is not really yours. It can be taken or frozen by the government just when you need it. Maybe it is not a good idea to keep too much money in the bank, especially when the next financial crisis comes!
