In India btc is very new concept. Only few peoples are use cryptos and exchanges. They know BTC but don't familiar with the term of cryptocurrency and blockchains. So this is the time when Scammers play their tricks.
In middle of 2019 when I was new in this crypto platform I joined a whatsapp group where I got a message from a man who offers me a btc,eth any crypto doubler site, I fall that trap but in less time I got the scam and block him. Although many sites who offers some dollars and get our kyc documents which is I think is a scam.
