I know you didn't ask me, but i just wanted readers new to the market to be sure that Golem is not a storage platform. It is a platform to allow you to sell your computers processing power to users over the Golem Network. So there is no comparison to Siacoin or Fileshare technology wise.
If you were speaking of price alone though, Golem is on a hot streak right now for sure. I hope you bought some 9 months ago when you posted this lol.
