Consider to raise minimum investment to 0.01 BTC. The current margin of 0.001 BTC is too low. I think it is time to scale up. Would like to know other player's opinion as well...
Well... that is a nice suggestion. But, it would probably be better to wait a few more days before implementing it. People like to test the authenticity of the site with low amount, especially when so many scams are around in this industry.
Keep up the work and generate interest. That's all.
