This is ridiculous, this requirement is designed to make players lose their deposited money. It should be highlighted on the main page of the site, otherwise players will feel be trapped if they did not know about it before they make deposit.
Much more better, this requirement should be removed.
We accept 1 confirmation for deposits, so yes you must play a little bit due to higher risk of fraud. It's common practice for BTC gambling sites.
Common practice for btc gambling sites? Can you give me a list of those btc gambling sites that has the same rules/terms with yours in which players need to wager 3x of their deposit before they are able to withdraw?
