Do online casinos support bitcoin?

I'm curious to know, do online casinos nowadays actually support the use of Bitcoin for transactions? With the rise of cryptocurrency, it seems like it would be a convenient and secure way to fund one's casino account. Is this widely accepted across different online casino platforms, or are there still some that haven't caught up with the trend? And if they do support Bitcoin, what are the advantages and disadvantages of using it compared to traditional payment methods?
