1. Is cryptocurrency safe for beginners to use?
Cryptocurrency can be used by beginners, but it carries significant security and financial risks. Users need to understand wallet security, scams and irreversible transactions before transferring or investing substantial amounts.
2. How much cryptocurrency was stolen through hacks in 2026?
According to TRM Labs, attackers stole approximately USD 972 million across 207 incidents during H1 2026. Although losses declined from H1 2025, the number of recorded incidents more than doubled.
3. What is the difference between custodial and self-custody wallets?
A custodial wallet relies on a company to manage private keys, while self-custody gives the user direct control. Self-custody reduces dependence on intermediaries but places responsibility for protecting keys and recovery phrases on the owner.
4. Can a cryptocurrency transaction be reversed if I make a mistake?
Blockchain transactions are generally irreversible once confirmed. Sending cryptocurrency to an incorrect address or incompatible network can result in permanent loss, which is why beginners should carefully verify transaction details before sending funds.
5. How can beginners reduce cryptocurrency security risks?
Beginners can use strong authentication, keep recovery phrases offline, verify wallet applications and avoid guaranteed-return investment schemes. Starting with small amounts and sending test transactions before larger transfers can also reduce avoidable mistakes.
