Bitcoin & Co.: Technology, price mechanisms and the market beyond number one
Bitcoin is no longer just “digital play money” for nerds. Since the establishment of spot ETFs and the full implementation of European MiCA regulations, the cryptocurrency has arrived in the institutional financial sector. But how does this “digital gold” actually work technically?
In this article, we’ll take a closer look at what drives the price in this more mature market phase and what alternatives still play a role today.
A deep dive.
The engine room: How Bitcoin works technically
Market dynamics: What influences the Bitcoin price?
Previously, it was tweets from Elon Musk or Chinese bans that steered the price. By 2025, the influencing factors have become more “mature.”
A. Supply and Demand (ETF Effect)
Since the approval of major spot ETFs in the US (by BlackRock, Fidelity, etc.), billions in institutional capital have flowed into the market. These funds need to buy physical Bitcoins to cover their holdings. If the supply decreases due to the halving, but demand from ETFs and savings plans remains the same or increases, the price must mathematically rise.
B. Macroeconomics & Interest Rate Policy
Bitcoin is now strongly correlated with global liquidity.
- Interest Rate Cuts: When central banks (FED, ECB) cut interest rates, money becomes cheaper. Investors are seeking yield and fleeing government bonds into risk assets (stocks, tech, crypto).
- Inflation protection: Many companies use Bitcoin as a hedge against currency devaluation.
C. Regulation (Legal Clarity)
For a long time, regulation was a bogeyman. By 2025, it will be a driver of share prices. MiCA (Markets in Crypto-Assets): This EU regulation has made Europe the safest haven for crypto companies. Banks are now officially allowed to offer custody services, which strengthens the confidence of conservative investors.
Beyond Bitcoin: The most important altcoins
While Bitcoin is considered “digital gold” (a store of value), other cryptocurrencies have different functions. They are called altcoins.
Ethereum (ETH) – The World Computer
Ethereum is the second-largest cryptocurrency and technologically completely different from Bitcoin.
- Smart Contracts: Ethereum enables programmable contracts. Applications (DApps), such as decentralized exchanges or lending platforms (DeFi), are based on these.
- Difference: While Bitcoin is “dead” money that you hold, Ether (ETH) is the “fuel” to use the Ethereum network.
Solana (SOL) – The High-Speed Alternative
Solana has firmly established itself as a competitor to Ethereum by 2025.
- Advantage: Extremely fast and inexpensive transactions.
- Disadvantage: The network is considered more centralized and less stable than Ethereum or Bitcoin. It is often used for gaming applications and NFTs.
Stablecoins (USDT, USDC) – The Bridge to the Dollar
Perhaps most relevant for everyday office life: stablecoins.
- They are pegged 1:1 to currencies such as the US dollar or euro.
- They offer the speed of the blockchain without the volatility of Bitcoin. They will play an increasingly important role in international B2B payments by 2025.
How can anyone participate in the world of cryptocurrencies?
In 2025/2026, access to cryptocurrencies will be easier than ever. You no longer need to be an IT expert to become part of the ecosystem. The market has professionalized, and the barriers have fallen. Here are the three most common ways to get involved today.
A. The Investor’s Path: Buy, Hold, Savings Plans
This is the classic entry point for 90% of people.
- Crypto Exchanges & Brokers: You can exchange euros for Bitcoin via regulated platforms (such as Bitpanda, Coinbase, or the German stock exchange Stuttgart Digital). Important: Thanks to MiCA regulation, you now have to fully verify your identity everywhere (video identification). “Anonymous buying” is a thing of the past with reputable providers.
- The ETF Path: Those who don’t want to deal with the technology can simply buy crypto through their regular brokerage account. Bitcoin ETPs, or ETFs, are tradable with almost every online broker (such as Trade Republic or Scalable). You participate in the price movement but do not physically own the coins.
- The savings plan strategy: To offset the high volatility, many investors use automated savings plans (dollar-cost averaging). Purchases are made automatically starting from as little as 10 or 20 euros per month – regardless of whether the price is currently high or low.
B. The “Pro” Way: Self-Custody and Staking
Those who want to delve deeper leave the exchanges and take control of their coins themselves.
- Be your own bank (wallets): With a hardware wallet (like Ledger or BitBox02), you store your private keys offline. The principle “Not your keys, not your coins” still applies in 2025. This protects you from the bankruptcy of trading platforms.
- Staking (earning interest): On networks like Ethereum or Solana, you can make your coins available to the network for security (“staking”). In return, you receive a kind of dividend (rewards). This is often done with a single click directly in the wallet app, but it comes with tax implications (in Germany, a holding period of often one year is required for tax exemption).
C. The Career Path: Working in the Web3 World
“Getting involved” doesn’t have to mean investing money. You can also invest your time and skills. The sector is desperately seeking personnel!
- Non-Tech Jobs: Blockchain companies don’t just need programmers. Lawyers for compliance, marketing managers for community building, and controllers are in extremely high demand.
- Education: Those who pursue further education in blockchain topics today (e.g., certificates from the Frankfurt School of Finance or online courses) are enhancing their resume for the modern job market.
Conclusion and Outlook
Critics and media educators warn of the negative consequences of a blanket ban:
Organizations such as the Federal Agency for Child and Youth Media Protection emphasize that, according to Article 17 of the UN Convention on the Rights of the Child, children have a right to participate in media. A ban for those under 16 would exclude them from an important social communication space. Critics fear that a strict age limit would leave young people unprepared for the digital adult world. The focus should instead be on enhanced media literacy in schools and better parental guidance.
Due to the ease with which such a ban can be circumvented, many fear that the law will only have a symbolic effect instead of providing genuine protection.
