Cheapest way to buy Bitcoin.
The five cost layers
| Cost layer | What it is |
|---|---|
| Spread | The difference between the market price and the price you're quoted. Often the largest hidden cost. |
| Platform fee | A flat or percentage fee the exchange or app charges on the transaction. |
| Network (miner) fee | The on-chain fee paid to process the Bitcoin transaction; varies with network congestion. |
| Payment-rail fee | Costs from how you pay (card, ACH, wire, instant transfer) — card purchases usually cost more. |
| Withdrawal fee | The fee to move Bitcoin off the platform to your own wallet. |
Why "no fees" claims are misleading
An exchange advertising "zero trading fees" can still charge a wide spread — meaning you pay more per Bitcoin than the market rate. The total cost is what matters, and it can only be compared on the confirmation screen, where all layers should be disclosed before you approve.
How to actually compare costs
- Check the effective price — how much fiat leaves your account per unit of Bitcoin received.
- Add every disclosed fee (platform, network, rail, withdrawal).
- Compare on the same day — network fees and spreads move.
- Factor in the payment method — a cheaper platform with a card surcharge can cost more overall.
Custody matters too
The cheapest platform isn't always the safest. Leaving Bitcoin on an exchange means the exchange controls the keys. A non-custodial wallet gives you control of the keys but full responsibility for the recovery phrase. Price is one factor; custody model is another.
What is always true about Bitcoin
Bitcoin and other digital assets can lose value rapidly and are not bank deposits or FDIC insured. Past price moves do not predict future ones. The FDIC's fact sheet is explicit that deposit insurance does not cover crypto assets.
Where Kronos fits
Kronos includes a non-custodial wallet for supported digital-asset sends and receives where enabled, meaning you control the keys. Buying Bitcoin is a separate action that runs through whatever provider the current app flow names; the asset, network, fees, timing, and availability are shown before approval. KronosPay LLC is a financial technology company, not a bank. Read the bank-status page.
