Building a solid foundation and building lifelong assets
First study of coin investment!
A special and friendly guide to coin investment from an economic expert anchor.

The author of this book currently hosts 'Coin Newsroom' on Seoul Economic TV and has hosted numerous cryptocurrency-focused programs, including 'Today's Coin', 'Coin Rhapsody', and 'Coincast'.
Building on this career, as a presenter, I've had the opportunity to meet with various crypto industry professionals and investors, and closely witness their success stories unfold.
Also, analyzing the cryptocurrency market with them gave me confidence in this market beyond just trust.
The point is, 'one day this market will be recognized for its true value.'
And its value is now slowly being revealed to many people.


The author also found that a significant number of people have achieved financial freedom through coin investing.
What they have in common is that, while they had some luck on their side, they studied and understood this market faster than others.
As a reward, I have witnessed up close how others have accumulated wealth in just a few years that would take them decades, or even centuries.
They were the ones who recognized the value of this market before others and were the ones who confidently argued for it.

So, does that mean there are no more opportunities? No.
Even though the number of cryptocurrency investors has increased, there are still many people around us who do not recognize the value of cryptocurrency.
Additionally, many crypto experts still view the cryptocurrency market as a "market of opportunity."
That means there's still plenty of room to grab that opportunity.

The fact that Bitcoin ETFs have surpassed gold ETFs in just one year demonstrates the explosive growth in investor interest in Bitcoin.
Bitcoin ETFs have also performed remarkably in terms of trading volume.
According to data from The Block, Bitcoin ETFs have surpassed $5 billion in daily trading volume on several occasions.
This is a very high figure compared to traditional ETF products, demonstrating the high level of investor interest and participation in Bitcoin ETFs.
The success of a Bitcoin spot ETF goes beyond simply being an investment product.
Significant fund inflows, increased trading volume, and institutional investor participation through ETFs are boosting the credibility of cryptocurrencies and attracting more investors to the market.
Going forward, Bitcoin ETFs are expected to drive the mainstream adoption of cryptocurrencies and further increase their importance in the global financial market.

As of 2025, the market size of stablecoins exceeds approximately $200 billion and continues to grow.
In particular, USDT and USDC account for the majority of market share, and traditional financial institutions are increasingly attempting to utilize stablecoins.
Stablecoins are used in a variety of situations.
Cryptocurrency exchanges use stablecoins instead of volatile assets like Bitcoin or Ethereum to make trading more stable.
Additionally, it is gaining attention as a means of reducing the impact of exchange rate fluctuations and enabling remittances at lower costs than the existing banking system.

The ETF net inflow chart is an indicator that shows the difference between inflows and outflows of funds from ETFs based on a specific asset.
This plays a crucial role in understanding investor sentiment and institutional investor positioning.

· ETF Net Inflow: If the inflow of funds into an ETF is greater than the outflow of funds, it means that investor demand for the asset is increasing.
This is likely to be interpreted as a bullish signal.

· ETF Net Outflow: If more funds are flowing out of an ETF than are flowing in, it indicates a decline in investor confidence in that asset.
This could act as a bearish signal.
