Currently, there are 346 addresses that have more than 10,000 $RUNE as table below. Highest $RUNE owned by single address currenly is over 57M $RUNE and second place is 31M. There are 8128 addresses that have more than 0 balance currently, so whale made up of 4.26% of total active address.

So, for all these WHALE addresses, it seems that many of them provided to ETH.THOR pool with over 23M USD has been provided to this pool. This is most likely due to the currently on-going $THOR IDO pool. Second place was native $BTC with more than 15M USD and then followed by BNB.BUSD pool. IIRC, THORChain is the only place to offer this lucrative of return on Proof of Work asset like $BTC. Current APY is around 13~20% with impermanent loss covered if users left their LP for more than 100 days. BUSD also has quite lucrative APY as it is the most traded by volume hence more incentive to provide to this pool.
