It completely depends on what you're going to do with the Bitcoin on whether you should accept it. If you are selling goods or services, the method of payment does not matter a whole lot if you're going to convert it straight into fiat using one of the many payment processors available for this job. As long as you have factored in all the associated fees into the end price, you should probably accept bitcoin and other crypto because it's possibly another unique selling point you have over rivals. If you are accepting Bitcoin and keeping it, you are vulnerable to all the price fluctuations that come with it - good and bad.
