Kakegurui is a gambling base anime as well but in my opinion, it is not so good as Kaiji, If you would watch Kakegurui Losing is not that big of a deal, Even though it is particularly both gambling it is in a different level of Psychological aspect, While Kaiji has a risk involved in every time he loses, I say Kakegurui has a lot of fan service on it and if you're into Fan service and gambling at the same time, I suggest it but If you are into the story I think Kaiji is great in aesthetic in pure gambling.

I wish there are Anime Bitcoin base story but again there are not.
