Simply put, fiat currency is legal tender that derives its value from its issuing government rather than a physical good or commodity. The strength of the government that establishes the value of fiat currency is key in this type of money. Most countries around the world use the fiat currency system to purchase goods and services, invest, and save. Fiat currency replaced the gold standard and other commodity-based systems in establishing the value of legal tender.

Arbitrage trading is a relatively low-risk trading strategy that takes advantage of price differences across markets. Most of the time, this involves buying and selling the same asset (like Bitcoin) on different exchanges. Since the price of Bitcoin should, in theory, be equal on Binance and on another exchange, any difference between the two is likely an arbitrage opportunity.

Cryptojacking is a malicious activity, in which an infected device is used to secretly mine for cryptocurrencies. In order to do so, the attacker makes use of the victims’ processing power and bandwidth (in most cases this is done without their awareness or consent).

Multisig stands for multi-signature, which is a specific type of digital signature that makes it possible for two or more users to sign documents as a group.

The Internet is a constantly evolving technology that continues to innovate. So far, we’ve experienced Web 1.0 and 2.0, and there’s much discussion of what to expect from Web 3.0. Web 1.0 provided a static experience for users without the ability to create the content-rich sites we have today.

Crypto fundamental analysis involves taking a deep dive into the available information about a financial asset. For instance, you might look at its use cases, the number of people using it, or the team behind the project.

Liquidity is the measure of how easily you can convert an asset into cash or another asset. You may have the rarest, most valuable old book in your backpack, but if you're alone on a remote island, it will be difficult to find a buyer. On the other hand, if you'd like to buy $100 USD of BTC on the BTC/USDT pair on Binance, you'll be able to do it almost instantly without any impact on price. This is why liquidity is important when it comes to financial assets.
