It is an old method that some scammers use but it doesn’t mean that they cannot still adopt this method again to make victims of people who are new to cryptocurrency.
To always avoid being a victim of these kind of things it is good that you always download an application from the official website of the company and not from random links sent to you or links found on the internet.

Thanks for the heads-up, but I’m not familiar with CoinCarp or how big or small this crypto exchanges it. Nevertheless, it looks like the article is 2023 and it could be that some of the fake sites have been taken down, or new ones have pop up recently.
