Lotteries don't really go well, I think the reason is that it is quite slow unlike dice, slots, and all other casino games. Basically, in my opinion, the crypto users don't really like slow paced games. More of they want to quickly see results like how crypto does in terms of price changes which is nothing short of volatile and they can see results quite instantaneous, this is why I believe users have brought such mindset.
Good luck on your platform though.
