Are there problems with cryptocurrency?

Yes, of course.

Most of the best-known cryptos suffer from problems with speed, scale, cost, user interface, practical applications, you name it. Other cryptos replace these downsides with some sort of central authority, which kinda defeats the purpose of a decentralized network.

Fortunately, “problems” do not usually keep people from using things. All technologies have problems, right?Internal combustion is 150 years old and still sucks. Man-made electrical power is even older and causes all sorts of problems. Some say wireless technology causes cancer and destroys our society.

Even the wheel has its limitations.

People naturally understand this. Some will focus on the negatives, and that’s valid.It’s also irrelevant. Technology succeeds because people find it useful, not because it’s flawless. As long as it offers some benefit over the status quo, people will give it a shot.
