It’s been a bullish few days for Bitcoin. I would not be surprised to see it retest the $92,000 level. The next bullish move that I am looking for is a break and hold above all-time highs around the $108,000 level. This will take time.

5 Wealth-Building Lessons from Warren Buffett's Investment Mastery
How patience and principle transformed a $38 investment into a $168 billion legacy
Legendary investor, Warren Buffett, announced his retirement at the age of 94 this week.
Warren Buffett is someone that I have followed and admired throughout my 40-year investing journey.
Let's look at 5 financial lessons that retail investors can learn from 'The Sage of Omaha'.
1 Longevity and Patience
"If you aren't willing to own a stock for 10 years, don't even think about owning it for 10 minutes."
Warren Buffett took a long-term view to investing.
His journey to a net worth of approximately $168 billion at age 94 started with an investment of three shares in Cities Service Preferred at $38 per share when he was 11 years old. Most of his net worth has been accumulated after his 'normal' retirement age of 65. By being patient, wealth has compounded exponentially.
Retail investors can copy this philosophy with a simple 'buy and hold' long-term strategy - I do not intend to start selling any of my long-term ETF portfolio until I retire.
2. The Power of Index Fund Investing
"The best thing you could have done is just buy an index fund and never look at a headline again."
In 2007, Buffett offered a $1 million bet to the hedge fund industry!
He believed that a simple S&P 500 index fund, with low fees, would outperform the hedge fund industry, with what he described as exorbitant fees, over a 10-year period. Protégé Partners took him up on the bet. And lost!
Retail investors can copy this by investing in index funds through Exchange Traded Funds (ETFs) or Mutual Funds and holding for the long term - every month, I invest in a global ETF.
3. Contrarian Mindset
"Be fearful when others are greedy, and greedy when others are fearful."
Buffett believes that many investors view market price action in the wrong way.
While many investors sell during market corrections, Buffett views these times as opportunities for buying. He understood that investors should not be driven by emotions such as fear and greed. Buffett makes his buying decisions on intrinsic value, which we will examine in more detail next week.
Retail investors can copy this by having a long-term buy-and-hold strategy and looking for buying opportunities with any extra cash during downturns - I increased my monthly purchases during the recent market downturn.
4. Look for Companies with an Economic Moat
"A good business is like a strong castle with a deep moat around it."
Warren Buffett defines an economic moat as a term used to describe a company's competitive advantage over its competitors.
Coca-Cola is a great example of a company with an economic moat - it has a strong brand name and a secret recipe which competitors find difficult to accurately copy. Apple is another example which has its own ecosystem covering phones, tablets, laptops, watches, headphones and software - if you buy one Apple product you are likely to buy more.
Retail investors can look for opportunities that they come across in their everyday lives - I like technology and regularly look for investment opportunities in this sector.
5. Humility
"I'm happy there. I'd move if I thought I'd be happier someplace else."
Despite being worth over $168 billion, Buffett has lived in the same Omaha house he bought in 1958 for $31,500.
Whatever your income, the true route to wealth demands spending less than you earn. Warren Buffett was an excellent and extreme example of this by preferring simplicity and practicality over extravagance and not investing in huge mansions or flashy cars.
Retail investors can apply this to their own lives by spending less than they earn and investing the rest - I am happy to drive a Honda, but could afford a more expensive car.
Conclusion
I believe that all of us have a lot to learn from successful business people and investors. Importantly, even small retail investors can put the same techniques Warren Buffett used to good use, no matter the size of your portfolio.
Which is your favourite principle?
Which are you going to incorporate into your investment strategy?
As always, none of this is financial advice. Everyone should invest according to their personal circumstances, risk tolerance and financial goals.
