I was confused about cold card, coldkey and keepkey but it's all clear to me now.
Were yogg hacked by someone or yogg is really scammer?
Before, I knew him that he's like a reputable guy and didn't scammed anybody but this is happened all of a sudden.
Otherwise, you should force yourself to learn on how to protect your bitcoin because that’s the only way you’ll never be scammed and never end up losing.
The thing here is that when the victims have trusted the source himself. They've never thought that yogg will go sideways but with all of the proofs, it seems that he did.
