Introduction.

If you are a Bitcoin newbie, know that Bitcoin has enlightened the brightest minds of our times, who have translated the content of the 2009 Bitcoin whitepaper, and continuously improve on the execution of programming it into today's Bitcoin network.
Designed as a synthetic form of gold, Bitcoin has the characteristics of sound money, like gold, and was specifically programmed to be 'digital gold'. In the coming digital world and digital economy, connected by the internet of things and money, it is far more compelling as an anchor than bullion gold and will inevitably surpass gold's total market capitalization, yet without destroying gold's total world value of around 10 trillion USD.
In fact, Bitcoin is harder than gold, with a limited total supply of 21,000,000 BTC, whereas 2,500 tonnes of gold can be mined every year for the foreseeable future. After the bubble in Bitcoin popped when Bitcoin reached 20,000 USD in 2017, the retail investors were deeply concerned seeing their favorite asset drop down to below 4,000 USD. However, in 2020, the smart money like Wall Street, Institutional Investors, Pension Funds, Hedge Funds and Company Treasuries entered Bitcoin, boosting the demand side, whilst struggling with a diminishing supply, laying a sound floor under Bitcoin's price and market capitalization. The growing Bitcoin appetite will push Bitcoin to 1 million USD per coin and a minimum market capitalization of 10 trillion USD over the next decade.
The plumber's work is ready.
Bitcoin was born at the start of the Central Banks' first experiments with Quantitative Easing, an economic theory claiming to have an ability to print wealth in an environment without sufficient economic output. After almost a decade, the rounds of QE continue and the smart money that is now flowing into Bitcoin and other crypto currencies has a strong appetite for crypto assets that function as a hedge against the expected yet unstoppable side effect of QE: inflation and the destruction of fiat currency.
What started with Bitcoin, was soon followed by Ethereum which functions as a global network and an application layer that offers thousands of developers a network and an environment which to build on. The result: a tidal wave of all the possible money use-cases and their specific blockchain protocols. These will all be interoperable in the near future and make significant improvements when compared to the current financial systems. An army of computer plumbers have successfully laid out the blockchain architecture piping network. Since money has too many use-cases, these chains will be communicating with one another trough a process called interoperability.
Improvements in security will allow for crypto currency mass adoption and real use-cases as money will erupt.
One of the biggest challenges regarding blockchains is their security. Most of the banked people have a banking account, which is secured and insured by their bank. In the world of crypto currencies, you don't need banks, its peer-to-peer and its trust less characteristics, make you the banker. And this comes with risks. I predict that bio-metrics such as eye scans will further offer an extra layer in smartphone security development to prevent fraudulent players to steal your identity and money.
Currently a hardware wallet is the safest option to secure your crypto currency funds, stopping every attempt by any hacker that might have access to your phone number, email account or computer. Unfortunately, when you want to pay with a crypto currency, you will choose doing so by using your smartphone. This leaves a lot of room for smartphone security improvements, especially in the current days of SIM-scams.
The rapid growth in DeFi will push people into coins that offer them interest on their crypto holdings. This results in people taking more risk, trading between security and profitability. With the retail bank sector not offering savers any interest options, DeFi will continue to outperform the market and people will demand more security measures such as bio-metrics and AI behavior analysis to stop scammers in time.
2021 will be an interesting year!
