Just like you shouldn’t let a price drop influence your decision to buy crypto, don’t let a sudden price increase alter your long-term investment strategy. Even more importantly, don’t start buying more crypto just because the price is rising. Always make sure your financial bases are covered — from your retirement accounts to emergency savings — before putting any extra cash into a speculative asset like Bitcoin.
Cryptocurrency exchanges are vulnerable to cyber attacks that might result in your investment being lost forever — scams are always a possibility with cryptocurrency. Scammers frequently use social media platforms such as Instagram, Facebook and Twitter to dupe consumers into making these investments. If you believe you've been targeted, you should contact national reporting centers like Action Fraud in the United Kingdom or the Federal Trade Commission (FTC) in the United States as soon as possible.

A blockchain is spread across many computers that manages and records transactions.
Although few cryptocurrencies other than Bitcoin are widely accepted for merchant payments, increasingly active exchanges allow holders to exchange them for Bitcoin or fiat currencies — providing critical liquidity and flexibility. Since the late 2010s, big business and institutional investors have closely watched what they call the “crypto space” too.
