But Bitcoin is not flawless. Even though its design decisions are groundbreaking, they also put serious limits on how it may be used now and how it can change in the future.

Here is a closer look at Bitcoin’s greatest limitations, including delayed transactions, getting stuck in decision-making, and how the community is getting around them.

The Blockchain Trilemma: Security vs. Scalability vs. Decentralization

The Blockchain Trilemma is what limits Bitcoin at its core. One primer says that any cryptocurrency has a hard time balancing security, scalability, and decentralization at the same time. Bitcoin put security and decentralization first, but this made it less scalable.

That trade-off is why the Bitcoin network confirms transactions about every ten minutes. Six confirmations (nearly an hour) is the best number. This is fine if you have to move millions of dollars, but not if you only want to buy a cup of coffee. Visa can manage up to 65,000 transactions per second, whereas Bitcoin’s foundation layer can only handle about seven.

The upshot is that Bitcoin is better as a store of value than as a way to pay for things every day. However, this scalability challenge is precisely what layer-2 protocols aim to overcome by enabling fast, low-cost transactions off-chain. For those looking to understand how this works, the Bitcoin Hyper website provides ongoing coverage and analysis of these critical advancements.

Transaction Speed and High Fees

Bitcoin’s limited throughput leads to network congestion. Fees go up a lot when demand goes up. Around the end of 2017, the average transaction fee was more than $160 per transfer, which was when Bitcoin’s price went up to $20,000. BTC fees have gone down a lot since then (in 2022, they were as low as a few cents). However, people are still worried by how unpredictable they are.

Simply put, you can’t do small everyday transactions (like a $5 coffee) because that would create too many UTXOs and fees. This annoyance is still one of Bitcoin’s biggest problems.

Governance and Decision-Making Gridlock

It’s well known that changing the regulations for Bitcoin is difficult. Due to its decentralized nature, any big change, like making the block size bigger, needs a lot of miners to agree on it. In the past, that limit has been about 75% of the network’s hashing power.

Bitcoin Cash (2017) and Bitcoin SV are two forks that came out of this slow, controversial process since people couldn’t agree on how to scale. But these splits are worth less than 1% of Bitcoin’s market value today. Their relative failure shows how stiff Bitcoin is. It’s resistant to change, which ironically also makes it reliable.

Privacy Isn’t Perfect

Satoshi thought privacy was important, but Bitcoin’s openness has both good and bad sides. Anyone may see the public ledger that keeps track of every transaction. Addresses don’t have to be linked to names, but patterns can disclose who they are over time.

Pros say that this makes Bitcoin less private than many people think. In response, privacy-focused coins like Monero and Zcash were created to provide further anonymity. At the same time, Bitcoin users are using more tools like mixers and second-layer protocols. Bitcoin does have some constraints for people who want to keep their money private, though.

Usability and Education Gaps

Losing keys often means losing access forever. Also, a lack of understanding makes it hard for people to get started. For example, most people don’t know that Bitcoin can be bought in little sums called satoshis, which is why many people think it’s “too expensive” to possess.

This lack of information is made worse by differences in age and culture. Trying to explain Bitcoin can often feel like trying to explain cars to someone who just bought a new horse. Until wallets, exchanges, and Lightning apps become more intuitive, Bitcoin adoption will continue to face a steep learning curve.

Regulatory and Taxation Pressures

People who use Bitcoin still live in countries that tax and control it, even though it’s decentralized. For example, selling Bitcoin in Canada, even just to spend it, starts a taxable event. In other places, calls for more regulation show that people are worried that Bitcoin could hurt established monetary systems.

This conflict between Bitcoin’s lack of borders and national laws is unlikely to go away. Most governments don’t want BTC to take over, especially since printing money is easier.

Potential Threats

People have expressed concern about risks that could last a long time. In principle, quantum computing may compromise Bitcoin’s cryptography, but many people say that forks would change before that happens. Some people are worried about the centralization of ownership since big companies are buying up BTC. Sudden price dips because markets are overdue for a reset are also a constant worry.

These dangers are still more speculative than the more pressing problems of fees, scalability, and usability.

Can Bitcoin Adapt?

Even with these problems, Bitcoin has been able to change in amazing ways. Segregated Witness (SegWit) made it possible to handle more transactions, and the Lightning Network now lets anyone make payments almost instantly and for very little money. Users can always check out Lightning and start learning how to pay with Bitcoin while paying less than a penny in fees.

Bitcoin’s rigidity, which makes updates hard, may also be its best quality. It resists tampering, political capture, and reckless experimentation. Newer blockchains like Ethereum or Solana may innovate faster, but none have matched Bitcoin’s stability and trustless design.

Final Thoughts

There are problems with Bitcoin. It’s slow, sometimes costs a lot, is hard to modify, and isn’t as private as many people think. Its supply cap makes it more like digital gold and less like global cash. Also, knowledge, rules, and human mistakes, like losing keys or having a bad wallet, are still problems that people face every day.

Yet none of these limitations erase Bitcoin’s significance. Workarounds like Lightning, forks, and altcoins prove the ecosystem is alive and adapting.

Bitcoin’s biggest problem may also be what makes it unique: It doesn’t bend easily. That makes it imperfect for buying coffee, but powerful as a long-term store of value in a world still grappling with inflation, trust, and the future of money.
