Hey all!

I am an avid student of business, and a long-time bitcoin holder.  One thing I have noticed on this forum and in the bitcoin community more broadly is the presence of many "Bitcoin Casinos."  (I'm including all crypto here; not just bitcoin.)  Many, though not all, seem to be provably fair.

I'm curious to know -- how good of a business are these casinos?  I'd really love to hear from folks who have actually run or experimented with such sites! 

Here are some initial thoughts and questions that strike me:

* It seems that there are a number of these businesses; how does one get a competitive advantage over others?
* It seems like switching costs for the user are pretty low.  Combining this with the above makes me wonder how challenging they are together. 
* Are there network effects with these businesses?  In other words, does it matter how many other people are playing at the casino I am playing at?  (If I'm playing against the house.)
* At what volume does it actually make sense to run one of these?   (I'm sure this is a context-dependent answer - would love to hear perspectives!)
* I see a number of scripts available for sale.  Does anyone in the business actual buy these, or do people just do their own custom development?

Thanks in advance for insights and opinions!
