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??
I myself have never experienced it, but if the potential victims already know a lot about bitcoin should not be easily fooled, because let the bitcoin mode telfon fraud is rife, but should be now intelligent people and know the true characteristics of fraud, but we must also remain vigilant ,
