If you are talking about gambling then it can be any site because its only about like and not because of any particular site.And if its about investment in gambling site then thats a really good return.Here are some sites like crypto-games.net,fortunejack or moneypot,have you invested in one of these.
maybe he means investing in gambling site, because he says that he "invested" 1mbtc and a profit of up to 8mbtc, if you forget which website you use to invested. you can see the list of gambling sites that accept investment facility in gambling section, you might find the site again, and tell me what it gambling site, and we can give it a try
Where is sites list?
I've invested 1mbtc blockchain deducted some fees for transaction but site I'm talking about take no fees from what you've earned If I remember correctly there was a text withdraw at any times and I've got exact same amount I've earned. Bustabit deducts 300 bits for transactions. If anyone find that site or similar to it then please message me. Thanks
