Crypto basics FAQ
What is the difference between Bitcoin and Ethereum?
Bitcoin is designed to be digital money and a store of value, with a fixed supply and a deliberately simple design. Ethereum is a programmable network where developers deploy smart contracts, which is what makes DeFi, stablecoins and most crypto applications possible. Many people hold both for different reasons.
What is a blockchain in one sentence?
A blockchain is a shared record of transactions, copied across many computers, where new entries are added in batches and old entries cannot be quietly changed.
Is crypto safe to hold?
The assets themselves are as safe as your wallet security. The prices are volatile, so only hold what you can afford to see drop by half. The main way people lose crypto is not a network failure but a lost seed phrase, a scam, or a bad transaction approval. Start with Crypto Wallet Security.
