Yeah, HE only means you are going to lose your money faster on average. You may choose to play at freebitco.in because you like it for other reasons.
And I think the lottery tickets and reward points they give you when playing the multiply game decrease HE, am I right?
They don't change the house edge in a statistical sense but when making a comparison between sites you need to factor in the giveaways and bonuses. Reward points and lottery tickets have a value, then there is the multiply bonus and free roll bonus as well. Some other sites have jackpots, deposit bonuses etc. Just saying 'don't use this site because it has a high house edge' isn't taking in to account all factors.
