The seller's decision to charge you more because of the risk associated with accepting cryptocurrency is, in my opinion, the best course of action if they are not a cryptocurrency trader themselves and are only accepting your payment in cryptocurrency because you have chosen to do so. This is the only way to reduce the risk associated with accepting cryptocurrency due to it volatility nature. If I am also the seller, I will add additional fees in such case, if not I won't take it from you due to price fluctuations.why did you even choose to pay with crypto, though? Why not use fiat money?you should have Simply converting crypto to fiat currency.
As for me, I have not bought anything with crypto before, but I have seen many people purchase things online by using cryptocurrency. I also have a plan to try and use crypto to purchase something one day, but seriously, I don't like making any attempts with my Bitcoin investment because I will not like the situation after using my Bitcoin to purchase something. The price will now be rising unexpectedly, which is going to be a painful thing for me.
