Little useful advice here. $3k is nowhere near enough to start a profitable casino website unless you are a great programmer, brilliant at customer service and good at marketing. A combination not many people have.
I used to invest in Just dice. There was a large hiccup but overall it was very profitable. I belive I trippled my investment in a fairly short time scale. Ive not bothered since it moved to clams as I could end up with 10 times more clams and still lose money if the value of clams collapses, but I am still tempted.
I have never tried any of the other investment in gambling sites because I either didn't trust the site would exist 1 year later or there was not enough players or house edge to make the investment in the house bank roll risk worth the potential profit. Put simply if there is a 50% chance any site goes walkies with my bitcoins then I want to be able to make 200% in 12 months or I am not going to risk it!
I would love to know if there are any btc gambling sites that people are currently invested in that are making significant long term profits.
Im on the same boat. Got some spare BTC that I would like to invest instead of having 100% of my BTC sitting on cold storage. i was looking around at casino deals and there seems to be very few casinos that have survived for a long time. PrimeDice is probably the site I trust the most, it has proved over the years that it can survive while delivering a good experience. I remember Stunna is like a lot here because his sig campaign had great rates and ran for a long period, I wish it came back.
Anyway, I can't think of many sites that have survived more than 2 years, which is where I start considering a site to be solid at least in the cryptospace.
