Deflationary Tokens based on smart contract is a great way to boost the token volatility. Since the tokens are continuously getting lesser in number, the price will be always in swing. It will be interesting that how this coin will be adapted when total circulating tokens will be half of the total number of coins.
I understand deflationary token concept helps to reduce circulating supply and hence increase demand for the token, but then some new projects are having a big misconception about it. I bought one DEFI token on uniswap and sent it out to a centralized exchange since my main aim was arbitrage, 20% of the token was burnt upon that transfer to my greatest dismay. What kind of token architecture is that? Some new DEFI token are adding the deflationary concept to spice things up anyway.
