Sorry, I had to make one more comment on Leo
LeoCoin is a joke. I have to say I only spend a short time on reading about it, but everything smell about LeoCoin...
The 2 promoters, are former scammers in a pyramid-scheme... The website does not explain much about the improvements, its still not clear to me... and they reward people using the coin in an pyramid-like-scheme... Maybe they use an anonymity function that is 100%?? but still the coin smell of fraud! Sorry to say...
