Who dear goes on sistemkoin exchange for any serious business. Well, it's possible they lied about the sales, perhaps because they wanted to extract investors. Also, they might have told more lies upon lies. The amount they told the project team that they sold could have also been a lie. It 's been long I used sistemkoin, which was in the days that airdrops were so lucrative.  I also had some little problems then but was later resolved.
The project team that chose sistemkoin should have also researched, to know what they should go for.
