Honestly, I didn't try for this black market yet. Actually, I'm looking for a most promising ICO project from where I can earn some good cash. And SciDex looks like that project I am looking for. Anyones else going to invest on SciDex too?
Have come across few sites with same promotions, but its not encouraging to get into the sites or move further. Have much experience in scams and have lost much. So being more aware of issues and tackling them. I would better exchange bitcoin into my local currency and get the things i need either through online or getting into the necessary shops and purchase. This is more satisfying.
