I have found that in recent time btc phone scam has been increased a lot. Scams call people and pursue people to pay taxes and bills by btc or any altercoins. Even some asks to invest in fake coin also. Mainly the scam group target people over phone.
Has it been happened with anyone??
To my way of thinking, I heard recently about that, the scammers will encourage you to invest with them and they will bring you to their flowery words that once you invest it this will be the amount back to you and so on. That's why sometimes its really hard to trust someone in bitcoin because you did not know if they are really trust worthy orthey are only a scammers who will only used you and your money. so be careful to put your money in investment especially if you did not know that person or that project so better to research it first before enter in that kind of business.
