Unfortunately I cannot answer your question as I haven't done Caribbean since they changed the bonus. However, from reading your post, it is not clear whether or not you know about
cryptocounter or not. If you're not already using it, download it. Its free and it really helps for all the crypto sites.
One last note - I've been learning backgammon in the past week and have read every article I could find in the Archives from Other Gambling. Thanks for sharing your wealth of knowledge on this topic.
