I don't know my advise is good for you but if you run or promote a service, there are boards for service announcements:
Service Announcements
Service Announcements (Altcoins)
Why don't you think it wion't last long?
I guess this is a discussion thread.
He may mean that the current price trend of Defi tokens won't last as the profit that a Defi makes on transaction are low and for good profit they need to increase the volume which is hard to achieve for every defi out there. Defi on the other hand are here to stay and the more coin they freezes, the demand for the coins they are using would keep increasing while their supply keeps on decreasing. Which would lead to the boost of price of those coins.
