This is out of topic. What you describe is nothing more than trading to accumulate more coins. Here the topic is about the floating rate used by the 'accountless' exchange mentionned.
@ak_Merin94
20% seems too much, or rather too good to be true. Additionally, I checked the FAQ and the website says nothing about stopping exchanges when rates significantly differ (in a negative way)
In fact, it clearly says the opposite, during a swap you can receive more but you can also receive less
(and surely not a difference of 20%)
Finally, checking your post history, I don't buy your story but that's a nice attempt.
I agree with you and others who note that it's "too good to be true". Yet, what they try to describe, yet, due to their limited knowledge of finance and economics, is commonly called "triangular arbitrage":
