Cheapest way to stack BTC in the US in 2026?

Strike with Auto-DCA, withdrawn weekly to a Lightning Pay wallet over Lightning.

Can I withdraw from Cash App via Lightning?

Yes — Cash App supports Lightning withdrawals up to a per-week limit. Useful for sweeping balances cheaply.

Is Strike safer than Cash App?

Both are US-regulated custodians. Strike is a specialist (Bitcoin-only); Cash App is a Block subsidiary. Treat both as on-ramps, not vaults.

What if I'm outside the US?

Cash App's Bitcoin features are US-only. Strike covers selected EU, LATAM and Africa. Lightning Pay's MoonPay on-ramp works in 100+ countries.

Do I have to pay tax on Strike/Cash App withdrawals?

A withdrawal to your own wallet is not a taxable event. The original buy is logged; selling or spending is what triggers tax.

Strike vs Cash App for Bitcoin (2026)

Quick answer

Strike wins on everything Bitcoin-native: lowest fees, native Lightning, FedNow withdrawals, bill pay over Bitcoin rails. Cash App wins on ubiquity — most US adults already have it and it doubles as a peer-payment app. Both are custodial.

The third option most people miss

Use either as a fiat on-ramp, then withdraw the BTC to a non-custodial wallet like Lightning Pay so the coins are actually yours.

Real fees, not advertised ones

Both apps quote a small headline fee then add a spread. The all-in cost is what matters. Below: what a $1,000 BTC buy actually costs on each, plus the cumulative cost of a $200/week DCA over one year.

Scenario	Strike	Cash App
$1,000 single buy	≈ $5–8	≈ $25–35
$200 / week DCA, 1 year	≈ $55	≈ $270
Instant bank withdrawal $500	$0 (FedNow)	$7.50 (1.5%)
Lightning send $100	≈ $0.01	≈ $0.01

Lightning support compared

Strike — Lightning-first

Sends, receives, Lightning address (you@strike.me), invoice scanning, BTC-denominated and USD-denominated payments.

Cash App — Lightning lite

Send and receive only, daily limit, no Lightning address, no LNURL. Fine for casual use, limiting for power users.

The custody footnote (it matters)

Both apps hold your Bitcoin. Your access depends on their terms of service, their solvency, and their cooperation with regulators. The fix is simple: buy on Strike or Cash App, then immediately withdraw to a wallet you control.

1
Buy on Strike or Cash App
Use Auto-DCA so the buys are predictable and unemotional.
2
Set a weekly withdraw rule
Once your balance crosses a threshold, withdraw the lot to Lightning Pay.
3
Use Lightning where possible
Lightning withdrawals cost cents and arrive in seconds. On-chain costs more but is fine for larger lots.
4
Confirm receipt in self-custody
Coins are only 'yours' once they're in a wallet whose keys you hold.

Which one should you pick?

Long-term stacker

Strike — lower fees, Auto-DCA, Lightning withdrawals. Save ~$200/year vs Cash App on a typical DCA.

Peer-payment user

Cash App — almost everyone you know already has it. Use Lightning for the actual BTC sends.

Outside the US

Neither — Strike's international coverage is patchy and Cash App is US-only for BTC. Use Lightning Pay's MoonPay on-ramp instead.
