Published founding year: DOPA wins this cell

The official sinsa PR gives a founding date of July 2022, with service starting on 24 January 2023. cardz.game does not print a founding year, so the published date goes to DOPA.

Cash buyback and Original: Cardz wins these cells

Cardz prints 85–90% cash buyback. The DOPA How it Works page converts 100% of a card’s value into credits, and credits are spending power inside the platform rather than cash in your account.

DOPA also sells original-style packs, so neither side can claim originals as an exclusive feature. The difference is what you receive when you hand the card back.

Ship and grade: Cardz wins these cells

Cardz sends one graded card per pack, tracked and insured worldwide. DOPA charges a shipping fee shown on the request screen, quotes 7 to 10 days on its English page, and does not grade every pack.
