I've seen pretty good performance with my $SIM / Sim Power by DCity.io, Splinterlands LPs are performing pretty ok-ish and of course the Cubdefi/Polycub Pools by the #leofinance team are very interesting as well - but the price of Leo/Polycub/Cub got hammered hard since any of their launches, destroying my chances of making profits so far.

Out of the LPs on Hive Engine, the DEC:VOUCHER had the highest ROI so far. I gained ~20% in half a year so far, maybe I should have put more attention onto that one...
