no one knows exactly where the scam and what is not, except maybe he has the 6th sense may be hehe, the point back to dirikita each, we do something we really understand and we know. my advice is more careful, because it all depends what we do as well. yes so lah I never experienced it because I myself was not careful.
No,I have not yet been scammed because when I start here in bitcoin my friend told me to not be a impulsive especially I am investing because we did not know every people here so I did not trust immediately.All we need here in bitcoin is to be careful for us to not be scammed.So we should be wise here in bitcoin.
