But I'm interested to know: Is developing a BTC gambling websites considered to be profitable?
Can I expect people to pay attention to a new game?
Is the market maybe already saturated?
-> I think if you can run gambling platform smoothly and can insure security of bankroll than it will be profitable for sure.
-> Yes, new and pretty addictive game will always be in demand. Look at bustabit, satoshimines, luckyb.it etc they are successful because they have delivered games with pretty new concept and addictive.
-> Market for bitcoin only casino is still not saturated but if you are only planning to have dice, slots etc than market for dice site is saturated to some level.
