Advantages and Disadvantages
Advantages: It is decentralized, very secure, its transactions are transparent and globally accessible, and many see it as a store of value against inflation. Its liquidity and institutional adoption are growing (e.g., ETFs).
Disadvantages: Its price is very volatile, it can be complex for beginners, it faces regulatory risks, and losing the wallet keys means irreversible loss of funds. Additionally, its mining consumes a lot of energy.
