We can speculate on what value cryptocurrency may have for investors in the coming months and years (and many will), but the reality is it’s still a new and speculative investment, without much history on which to base predictions. No matter what a given expert thinks or says, no one really knows. That’s why it’s important to only invest what you’re prepared to lose, and stick to more conventional investments for long-term wealth building.

Unlike traditional currencies, cryptocurrencies exist only as a shared digital record of ownership, stored on a blockchain. When a user wants to send cryptocurrency units to another user, they send it to that user’s digital wallet. The transaction isn’t considered final until it has been verified and added to the blockchain through a process called mining. This is also how new cryptocurrency tokens are usually created.
The difference between a digital currency and a cryptocurrency is that the latter is decentralised, meaning it is not issued or backed by a central authority such as a central bank or government. Instead, cryptocurrencies run across a network of computers. Digital currencies have all the characteristics of traditional currencies but exist only in the digital world. They are issued by a central authority.
