All informations he gave were false. Just-dice is in CLAM only but other casinos offer to invest in BTC, the risk is big but the reward can be big too.
Better than just-dice i will try primedice,or look for casinos which offer good investment offers.. starting by investing small amounts..its all about luck afterall. And there are casinos if you singup you already have few satoshis or mbtc..i will search that.
