I acutally think that Golem is overhyped and that gridcoin does better at the moment. Boinc is around for years and has delievered a huge amount of computing time. The computing power of team gridcoin makes team gridcoin actually on place sixty of the top500 supercomputer list (https://steemit.com/gridcoin/@grider123/gridcoin-is-the-sixtieth-fastest-supercomputer-in-the-world).
And the fact that 51 % of the Golem tokens are owned by 5 addresses does not make it look better for me (Https://steemit.com/gridcoin/@sc-steemit/why-golem-falls-flat-compared-to-gridcoin-network#).
As I can say for me I go completly for gridcoin! If gridcoin fails I've still contributed to science and that feels good.
