How do Bitcoin, Ethereum, and other major cryptocurrencies differ?

Bitcoin (BTC) acts as digital gold for value storage and payments, using Proof-of-Work. Ethereum (ETH) is a platform for smart contracts and decentralized applications, now running on Proof-of-Stake. Ethereum supports more transactions (15–30 TPS) and complex financial solutions, while Bitcoin emphasizes security and scarcity.

How can users buy, store, and trade cryptocurrency safely?

Choose reputable platforms with two-factor authentication. Store the bulk of your funds in hardware wallets (Ledger, Trezor) and trading balances in hot wallets. Diversify your portfolio, avoid impulsive decisions, and beware of scams.

What risks come with investing in cryptocurrency, and how can they be reduced?

The main risks are high price volatility, lack of regulation, and fraud. To mitigate these, use trusted platforms, hardware wallets, two-factor authentication, diversify holdings, and thoroughly research projects before investing.
