Crypto for beginners: a plain-language starter.

Crypto for beginners starts with the concepts — not a specific coin or a price chart. Before you transact, understand wallets, keys, networks, custody, fees, and the risk you're taking. This guide gives you the vocabulary to read the rest safely.

What cryptocurrency actually is

A cryptocurrency is a digital asset recorded on a blockchain — a shared ledger replicated across many computers. Bitcoin and Ethereum are the most well-known examples. Each unit is tracked by address on a network; moving funds means broadcasting a signed transaction to that network.

Wallets and keys

A wallet doesn't "hold" coins the way a physical wallet holds cash. It holds the keys that authorize movement of coins already on the blockchain. There are two main types:

TypeWho holds the keysRecovery if you lose access
Non-custodialYouOnly through your recovery phrase. No support can reset it.
Custodial (an exchange)The exchangeThrough the exchange (email, ID, support) — but the exchange controls access.

Networks and addresses

Different assets live on different networks (Bitcoin, Ethereum, Solana, Polygon, etc.). An address is valid only on its own network. Sending Bitcoin to an Ethereum address, or using the wrong network, usually means permanent loss. Always confirm the asset, the network, and the destination address before approving a transfer.

Fees

Every on-chain transaction carries a network (miner or gas) fee that varies with congestion. Buying, selling, and transferring through an app adds platform fees and spreads. Read the confirmation screen to see the total cost before you approve. The "cheapest" platform is the one with the lowest total cost for your specific transaction. See cheapest way to buy Bitcoin.

The risk you take

Where Kronos fits

Kronos includes a non-custodial wallet for supported digital-asset sends and receives where enabled — meaning you control the keys. Buying and selling run through whatever provider the current app flow names, with asset, network, fees, timing, and availability shown before approval. KronosPay LLC is a financial technology company, not a bank. Read the bank-status page.

Primary sources

Is cryptocurrency safe?

Not in the way a bank deposit is safe. Crypto can lose value, is not FDIC insured, and mistakes (wrong address, lost recovery phrase) are usually permanent. Understand the risk before transacting.

Do I need to report crypto on taxes?

The IRS treats digital assets as property. Review current IRS guidance or a qualified tax professional for how your specific activity should be reported.
