I proposed something already similar like this back in November: > [@Proposal: Dynamic Surcharge Pricing for Fees on withdrawals over a changing amount](http://gov.yearn.fi/t/proposal-dynamic-surcharge-pricing-for-fees-on-withdrawals-over-a-changing-amount/7431): > > Testudo et Lepus [barlowtortoisehare\_400] [Of the Hare, and the Tortoise.](https://quod.lib.umich.edu/e/eebo/A26506.0001.001/1:5.2.119?rgn=div3;view=fulltext) Note: Testudo more formally refers to [a roman military formation](https://en.wikipedia.org/wiki/Testudo_formation), and not to the creatures belonging to the testudine family. The phrasing is entirely intentional, as the testudo formation was in fact both a defensive and offensive posture, which this could be. TL;DR: enable dynamically adjusting fees so that only fees are imposed market dumps, rugpulls, bulge bracket transactions, etc. vast majority of users wil… It is not gas expensive, the contracts are done for this sort of use case pretty much. --- _[View the full topic](https://gov.yearn.fi/t/proposal-adaptive-mgmt-fees-based-on-aum/9280)._
