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??
yes, there are many types of scammers in this industry including as you discussed. vigilance should be prioritized especially if someone is calling you who is reviewing crypto and bitcoin. it mostly makes no sense
Essentially you should never try to follow what they say, and if you want to invest better you buy it in exchange.
