Why do I say ExtStock Exchange (https://extstock.com/) is a big scam? Because of:

1. The price of BTC and ETH on it is much higher than other exchanges in order to attract people to deposit money into it.

2. You will not be able to withdraw money from the Extstock exchange.

3. The referral program requires you to deposit 5 USD to get back 40 XT tokens.

4. It has been reported on coinmarketcap.
