Mr. Taktak, you are known as a crypto expert. In which ways do cryptocurrencies differ from fiat currencies, and what problems do they solve for users?
The biggest difference is that fiat money is issued and controlled by central banks, while cryptocurrencies operate on decentralized networks. That means, no single institution has full control over supply, transactions, or accessibility.
For users, this creates several advantages. First, cryptocurrencies allow global transfers within minutes, without depending on banks or opening hours. Second, they offer financial access to people who may not have access to traditional banking systems. And third, assets like Bitcoin are designed with limited supply, which makes them fundamentally different from inflation-sensitive fiat currencies.
In simple terms: fiat money depends on trust in governments, while crypto depends on transparent code and network consensus.
Bitcoin, Ethereum, Tether, and Solana – is there a reason for the diversity?Why isn’t a single cryptocurrency sufficient?
Because different cryptocurrencies solve different problems.
Bitcoin was created primarily as a decentralized store of value. Ethereum introduced programmable smart contracts, which made decentralized applications possible. Tether serves as a stable digital dollar for trading and liquidity, while Solana focuses on speed and low transaction costs.
It is similar to the traditional economy: we also do not use one single financial instrument for everything. We have cash, stocks, bonds, payment systems and commodities — each serves a different purpose.
The diversity in crypto reflects specialization, innovation, and competition.
Bitcoin is the most widely recognized cryptocurrency. Which features set it apart from other cryptocurrencies?
Bitcoin stands out because it was the first successful cryptocurrency and remains the most decentralized and secure network in the market.
Its fixed maximum supply of 21 million coins creates scarcity, which is one of the reasons many investors compare it to digital gold.
Unlike many newer projects, Bitcoin has one very clear mission: preserving value independently of governments and monetary policy.
That simplicity is actually one of its greatest strengths.
Some central banks are no longer relying solely on gold reserves and are beginning to include Bitcoin in their portfolios. What factors are contributing to this rising interest?
Bitcoin is increasingly seen as a strategic reserve asset because it combines scarcity, global liquidity, and independence from political influence.
Gold has played that role for centuries, but Bitcoin offers similar scarcity with the additional advantage of digital transferability and transparent supply.
Another factor is geopolitical uncertainty. In times of inflation, debt expansion, and currency instability, institutions are looking for alternatives that cannot be expanded at will.
Bitcoin has entered that discussion because its monetary rules are fixed.
Over the next five years, how do you expect the role of cryptocurrenciesto evolve? Will we continue to see such a large number of different cryptocurrencies, or is the market likely to consolidate or expand further?
The market will most likely mature.
That means many weaker projects will disappear, while a smaller number of strong ecosystems will dominate. At the same time, new specialized projects will continue to emerge, especially in areas like payments, tokenization, AI integration and digital infrastructure.
So we will probably still see many cryptocurrencies — but with a clearer distinction between serious long-term projects and speculative short-term tokens.
The next five years will be less about hype and more about real utility.
