I opened electrum wallet for them. After some weeks, it was even yesterday, a friend of mine contacted me using Whatsapp, he told me what he saw online, that it is even possible to double bitcoin online. He wanted to double his bitcoin, I told him that it can be a scam that he should send me the link.
This is a good demonstration of how a lot of people don't view Bitcoin as money, they view it as some sort of magic bean that makes everyone rich. If you offer someone to double their cash or bank account, they would think it's a scam, but they don't have the same thinking when it comes to Bitcoin, because the field of Bitcoin is so new and different to them, that they are forgetting everything they owned with traditional money.
