i’ve done the similar thing that I have learned from our Meetup at the Bitcoin Brisbane the method that I use to select the 11 random words is from seedpicker.net , but I’m not hundred percent confident the seeds I selected have correct entropy. First thing is that I have rolled the dice 11 times and then selected the ticket raffle to choose the word. After selecting 11 and then putting them in the seats signer to get the 12th one. This is how I generated my seed. What should I do to check the entropy that is a?
