Currently on the cryptocurrency market, many coins appear to follow Bitcoin (BTC), including many fraudulent projects,
 appropriating investors' money. The most typical are two projects BTCONE and Bitcointoken (BTK) and have now been transformed into BTCT. These two projects are essentially one and the team members of both projects are one.

At first, they took advantage of the relationship with a number of exchanges and e-wallets (I think there's a group interest in it) that launched the coin, put it on the exchange, created Bounty or airdrop programs to entice investors to buy their scam money.
After selling and earning a certain amount of money, the sale becomes more difficult, they create the so-called SWAP with blatant fraud, 90% of investors cannot Swap and of course the amount That will permanently disappear with investors, and the crooks have created new coins with a lower total circulation. Not only do investors not swap tokens for a limited time, they create new coins with a total supply that is 2 or even 10 times higher, but only swaps for investors with a swap ratio of 1/1. .
To deceive investors, they first created a telegram group and gathered everyone who invested in the project, then deleted all these people in the public chat channel, after deleting all people. In this general chat channel, they introduced the so-called swap on the common chat channel and of course almost all investors could not convert their tokens invested.

I also could not understand that some exchanges like Coindeal, or STEX were linking to cheat investors with them while receiving warnings.
