The minimum deposit at Gamdom is $1 equivalent crypto. That figure is the cashier minimum, not the practical minimum. The practical minimum is the cashier minimum plus whatever the network fee is on the coin you send.
Gamdom supports 11 cryptos. The cheapest networks to deposit on, in our experience, are TRC-20 USDT, Litecoin, and Bitcoin Lightning where available. ERC-20 USDT and on-chain BTC will cost more in fees, sometimes enough to make a small test deposit not worth it.
If you are sizing a first deposit specifically to test Gamdom before committing real bankroll, $20 to $50 on a low-fee network is the practical floor. Anything smaller and the network fee starts to be a meaningful percentage of the deposit, which makes the test itself a bad bet.
The full payment-method breakdown, including which coins clear fastest at the cashier, is on the Gamdom payments page.
Score breakdown across seven categories, deposit-tested screenshots, payout times we actually measured, and the bits the operator does not mention in their welcome banner.
