I did some researches. bankless Dao has 5 type of member roles.

Guest Pass = 14 day pass with access similar to Level 1 Level 1 = Member, has 35,000+ $BANK Level 2 = Contributor, voted by community, same $BANK requirement as Level 1 Level 3 = Whale, has 150,000 $BANK Level 4 = Liquidity Provider, 250 Uniswap V2 BANK/ETH LP tokens, for example

in below query i check last 100 days members and whales. it shows that approximately members are about 1500 and whales are about 300.
