I cant fully agree if disabling faucet can affect the site negatively. The faucet amount is just so small amount while users can earn much more through the rainbot, challenge, forum rewards, and many other promotions. Real gamblers wont really care about faucet in general imho so I think it is OK to remove the faucet.
Maybe they're spending so much on faucets that it's reducing their profits and those amounts could be spent on something better (ads contests,etc) . I also think it's reasonable for them to remove the faucet because the main reason for it is to play without a deposit and we can still do it since they don't have a minimum amount in all of their games. With that said, their faucet becomes a bonus and unncessary.
if you've spent a few minutes in any online crypto casino, you'll come to notice there's a fair number of users that will literally sit on the site and farm the faucet trying to make meager amounts to withdraw over and over. it's only a few cents, sure, but factor in that there might be dozens, hundreds of users trying this multiple times a day and it adds up.
I think the faucets will pretty soon be a thing of the past. Basically the faucet was invented to try out Bitcoin without having to go thru the hassle of buying it or mining it. And the purpose of the faucet with a gambling site was to try out the site or the type of game before actually going thru the hassle of doing a deposit. Because if someone didn't like dice, or the speed of the site, or the features of the site it would be annoying having to make a deposit, pay a miner fee, and then the site would have to pay another fee for the withdraw. Hence why the faucet was invented.
However as 2017 rolled around, there was massive amounts of abuse with the faucets. Basically I think it was like 0.1% or so that abused it but they took 99% of all the faucet payouts and the site had no other choice but to disable it. Because those faucet abusers almost never made a deposit and contributed nothing to the gambling website.
Hence why you will see more and more sites use tokens or some type of demo play to test out the site. Since it was becoming very troublesome and took too much man hours to sort thru all those withdraw requests which were purely out of faucet earnings.
honestly, faucets are just a continuation of a tradition at this point; if the casinos really wanted to they could easily just put play money up for the users to test the site with. a sikmilar solution was implemented by bitvest, where the faucet is purely play money now (they can be redeemed for actual coin at a certain threshold) in the form of tokens.
