What is an Altcoin?

The cryptocurrency industry has expanded rapidly since Bitcoin's rise in 2013. Today, over 10,000 active crypto assets exist worldwide, with Bitcoin maintaining its dominance in market capitalization. This diversity led to the term "altcoin"—short for "alternative coin"—referring to all cryptocurrencies other than Bitcoin. This guide explores altcoins, their categories, pros/cons, and investment strategies.
