This comment is spot on.
I think the best option is to save in Lightning, but ignore the option of storing within the exchange.
You can accumulate your Lightning SATS in a self-custody wallet, and when you have more than 100,000 SATS, you can start building your UTXOs on the main chain.

Two types of fees to think about separately: the exchange's trading fee and the Bitcoin network withdrawal fee.
The bigger issue for small amounts: on-chain withdrawal fees
At 5k sats (~$5), a typical on-chain withdrawal can cost 200–1,000 sats in miner fees depending on mempool congestion — that's 4–20% of your stack just in network fees. Frequency makes this worse: weekly withdrawals = 4x the on-chain fees of monthly.
Best options for low income stacking:
1. Accumulate, withdraw less often
Buy weekly if that's your discipline, but only withdraw on-chain once a month (or less). Let it sit on the exchange temporarily. Check mempool.space for low-fee windows (weekends often cheaper).
2. Use Lightning for withdrawals
Some exchanges support Lightning withdrawals — fees are near-zero regardless of amount. Then receive into a self-custodial Lightning wallet like Phoenix or Breez.
3. Strike or similar low-fee services
Strike charges ~0.5–1.5% trading fee and supports Lightning withdrawals. For 5k sats that's a much better deal than paying 1,000 sats in miner fees.
Bottom line: Weekly buying is fine for discipline. Weekly withdrawing to cold storage is expensive at 5k sats. Stack on exchange, withdraw monthly or less, use Lightning if available.
