I am well aware of coins with controlled inflation like BTC, where a finite number of coins will be generated at a controlled rate. Very recently I came across deflationary tokens where coins are destroyed whenever a transaction is made and they will end at some time.
My question is what is the purpose of creating such coins? Are they worthy enough to be invested ?
I believe that many of these are born for speculative purposes and therefore I advise you to be careful, it is also true that I have read something about it in anticipation of ETH2... I don't know but I don't like the idea.
