Hey guys. I currently have a little over 2btc at my disposal. I was wondering what the safest and best way to flip that into 4btc, and the 4btc into 8btc, etc. I really want to save up for a powerful ASIC, and am stumped as to how to turn this into more. I've tried exchanges, but end up losing more than I gain. Im looking for a solid and sure way to make coin off of what I have currently. Thanks!
