In my opinion, I think referral bonuses are typically waste of one's time because of its processes that seems so impossible to claim and recently I came across a thread
https://bitcointalk.org/index.php?topic=5437603.0 seeking for Casinos with paid referral bonuses and I tool out time to read most of the responses there and they all seem impossible to claim referral bonuses.
I wish to know if anyone has successfully claimed referral bonuses and how easy was the process and what Casino did you claim those bonuses
I had a single referral bonus experience that made me a lot of money, but that was a long time ago.
In fact, it doesn't exactly fit into the casino category, but it still has something to do with the gambling area... I'm talking about freebitco.in
It was a long time ago, between 2017 and 2019, that I "spread" my link across several places and this earned me a very significant amount of money in a short time.
Other than that, I confess that I didn't spend much effort in publishing links to other casinos, so I'm not sure if they are profitable or not, but one thing I know for sure: the sites profit much more than the users who publish them.
