What should the minimum liquidity value threshold be for AMM pools to be listed in the LP protocol fee vote?

For context there were 98 AMM pools listed in the first protocol fee vote (https://vote.loopring.io/#/proposal/0x35ed127d0b297b9d848de4ffc054951134c3afe6c458f80859fc4ffb1600066b). Many felt that future proposals could be improved by reducing the number of options. In addition, establishing a minimum liquidity value may provide an incentive for less liquid AMM pools to acquire more liquidity in order to be listed in the quarterly protocol fee vote.

Please note that protocol fee LP voting will take place quarterly, and any pool that receives a minimum of 10% of the vote will be rewarded for the quarterly fee distribution.
