01Flip stage

eBay: queued

$1 → $1,000. Buy underpriced goods, resell online. Zero-risk doublings — you're paid for hustle, not luck.

  • eBay: Marantz 1122DC draft ready at your $10k ask — listing goes live the moment the seller account finishes phone signup + real photos.
  • Free/clearance finds → Facebook Marketplace & Mercari. Small items first to build feedback.
  • Rule: never pay more than 50% of a confirmed sold comp.

02Bonus stage

Sweepstakes: live daily

$1,000 → $10,000. Harvest money the house gives away: sign-up promos, bank bonuses, cashback stacking.

  • Sportsbook promos via the betting page affiliate links — +EV by design.
  • Daily sweepstakes entries already running — free shots at cash prizes.
  • Bank account bonuses ($200–$500 each) when the bankroll covers minimums.

03Scale stage

Shopify: live · 5 products

$10,000 → $1,000,000. Stop doubling dollars — multiply customers. Roll profits into assets that sell while you sleep.

  • CyberGrokr Shopify store — live with 5 products. Add print-on-demand merch (zero inventory cost).
  • Gumroad books ($27 / $10) — pure margin on every sale.
  • Affiliate engine: DiscoverCars, Shopify Affiliate + 10 more programs in the pipeline.

House rules

  • Start: $1.00. Goal: $1,000,000 (20 doublings).
  • Log every flip — cost, sale, venue. If it's not logged, it didn't happen.
  • No whole-bankroll bets on negative-expectation games. Doublings come from margin, not miracles.
  • Reinvest profits into the next stage; don't lifestyle-creep the bankroll.
  • Sweepstakes and promos are free entries — they never risk the bankroll.
