the number of posts of this op (1) indicates to some extent the depth of his research into btc. It is plain nonsense imo what he has stated. it is true that very early adopters paid more btc for goods when the price was a few dollars or less. But if that was the going rate and you received your item that is not a "scam". Similarly today because of the phenomenal increase in btc value as a currency you pay less but again if you receive your item its not a scam. mining including cloud mining is something every participant has to decide if the roi is suitable for them. Again its an individual choice to do it or not so that is not a scam either!.
