Hello!
Please be aware that koinkartel.com and KoinKartel - this forum member - are scammers.
I've agreed with them on a project, paid 50% and they just disappeared.
If you know this guy - please let me know.
Thanks!
What the project that was and also give us more details. Maybe it's you misunderstood something? Anyway, hope that 50% weren't a huge stack of money.
