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.
How good is the deflationary when the market is highly volatile? See what happened on AMPL, they are now barely surviving due to the negative rebase of the coin price.
I am fomo indeed but losing 100$ in the process is not good. Also you will noticed that the decrease of coins are likely eat your stuck in the end. Only whales can support its volatility by having tons of coins and will sell during rebase.
So why not swim with whales, get profit and quit before its too late. One need to be pro-active to study and make decision about such Deflationary tokens before its too late.
As far as AMPL is concerned, its doing good with 30 million $ turn over in last 24 hours.
