So, all in all the more affiliates you have the more type of ways you can win, lottery is of course luck based compared to others (you get a ticket but you may win nothing) but all other options are amazingly certain, even just a click of free faucet that is guaranteed to make you and your affiliate money (no chance to lose, its just free money giveaway) is good to have. That is why I always try to put banners on crypto websites with my link to maybe get couple more from the money I make from my affiliates.
So, basically whatever your affiliate does on freebitcoin you make some profit from it and that's uncanny. Normally casinos only give you money on either losses (common) or maybe revenue but that's it.
