Cheapest Way to Buy Bitcoin in 2025

Don't pay more than you need to. Here's how to maximize your BTC for every dollar spent.

₿

Cheapest Method

ACH deposit (free) + Binance.US (0.10%) + limit order = 0.10% total. On a $1,000 purchase, you pay just $1 in fees. Compare to Cash App at ~$20.

Total Cost Comparison: $1,000 BTC Purchase

Method Deposit Fee Trading Fee Total Cost
Binance.US + ACH $0 $1 $1
Kraken + ACH $0 $1.60-2.60 $1.60-2.60
Coinbase Adv. + ACH $0 $4-6 $4-6
Coinbase Simple + ACH $0 $15+ $15+
Cash App — ~2% ~$20
Any + Debit Card $25-45 +$1-15 $26-60

The Optimal Strategy

  1. 1
    Deposit via ACH bank transfer — Free on all major exchanges. Takes 3-5 days but many offer instant trading.
  2. 2
    Use Binance.US or Kraken — Lowest trading fees (0.10-0.16% maker).
  3. 3
    Place a limit order — Pays maker fee, saves 30-50% vs market orders.
  4. 4
    Keep on exchange or withdraw via Gemini — If withdrawing, use Gemini's 10 free monthly withdrawals.

What About Convenience?

If speed matters more than fees:

  • Same-day purchase: Wire transfer ($10-25) + exchange trade. Total ~$15-30 on $1K.
  • Instant purchase: Debit card (2.5-4.5%). Total ~$25-45 on $1K. Only for emergencies.
  • Quick & reasonable: Coinbase with instant ACH trading. Free deposit, trade immediately, 0.40-0.60% fee.

Avoid These

  • ❌ PayPal/Venmo — High spreads, can't withdraw BTC
  • ❌ Bitcoin ATMs — 5-20% fees, absolutely brutal
  • ❌ Credit cards — Cash advance fees + exchange fees
  • ❌ "Simple buy" interfaces — Convenience tax of 1-2%

The Bottom Line

ACH + Binance.US + limit order = 0.10% fees. If Binance.US isn't in your state, Kraken at 0.16% is the next best. The difference between optimal ($1 per $1K) and lazy ($50+ per $1K) adds up fast over time.
