Frequently Asked Questions
Which cryptocurrency should a beginner start with?
Most beginners are best served by understanding Bitcoin and Ethereum first β the two largest and most established assets β before considering smaller altcoins, which carry far higher risk and require careful evaluation.
Are cryptocurrencies a safe investment?
All cryptocurrencies are volatile and uncertain. They can deliver strong long-term returns but also severe losses. The disciplined approach is to invest only what you can afford to lose, secure your holdings properly, and hold for the long term.
How do I keep my crypto safe?
Buy on a reputable, regulated exchange, secure your accounts with app-based two-factor authentication, store significant holdings in a cold wallet you control, protect your recovery phrase offline, and never share your private keys with anyone.
