How to dilute SBD Steemit into Bank Account?

One of the things I do not understand is how to dilute SBD Steemit into a Bank account. this still makes me confused how to melt it because I am still a new user in this steemit. what SBD Steemit can be cashed directly into a bank account? what to do first in exchange can be channeled into a bank account? it makes me wonder how to convert steemit / steemit results. For stemian friends who have converted Steem / SBD results to Bank Account, to be able to share with me and other new friends, steemit users how to dilute Steem / SBD steemit.
