Why do we have rates for selling bitcoin and other cryptocurrencies lower than on other platforms?

 After analyzing the cryptocurrency rates on other platforms that you all know very well, the idea was to create Cryptoda as a convenient and easy-to-use cryptocurrency exchange platform with the lowest rates.
 The low rate of buying Bitcoin and other cryptocurrencies was pretty easy to do!
 The fact is that similar platforms place overvalued rates on the sale of Bitcoin and other cryptocurrencies, which are easy to kill and sell cryptocurrencies 1-1.5% below their prices.
 This does not mean that we trade in a minus!
 We took the Binance exchange as the basis of the courses of cryptocurrency and we step from this course.
 It turns out that anyone who wants to sell or buy a cryptocurrency can become an exchanger on our platform and set the rate lower than on popular platforms.  This makes it possible to earn both small and large exchangers.

 Another feature of Cryptoda is the CDA token.  Which can not be bought, but its growth is inevitable.
 For each exchange, users receive 0.5% of funds in CDA tokens of the amount of exchange.  That is, the tokens are really supported by the exchange and they can be obtained only by making an exchange.

 Tokens can be exchanged for cryptocurrency or used to extinguish the commission of the exchanger, which is already minimal.

 Why is the growth of tokens inevitable?
 1) a limited number of tokens.
 2) The accrual of tokens will decrease over the exchange with an increase in the rate.  Now the fixed price is 1CDA = $ 1.
 3) Burning tokens for a commission in exchange (the principle is the same as on the Binance exchange)

 And most importantly: this is an ideological project, so the commission is minimal and courses are low.
