No I do not feel shameful for it at all because its something that I love to do and I never do it with large amounts.
I don't feel shameful for being a gambler because it hasn't discredit me as a person and gambling is not a crime which i commited all I just wanted is fun and stress reliever unless I steal the bitcoin I used to gamble, that's probably shameful feelings. As long as you enjoyed playing for good purposes without being addicted and you can manage well with self control then nothing to shame with.
