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.
Unfortunately, there are still gullible people. Especially those who crave easy money. In hope, people do stupid things, give up their data, security keys and scammers still thrive! As long as there are fools, there will be new schemes! Once my friend was offered to split the income from an Internet project in which 3 bitcoins were frozen. The person needed an Internet bank card for cashing out, He believed that they wanted to share with him!) As a result, the account data was changed and he lost access to his card forever! Be careful and do not believe in luck!) Nobody just gives anything!
