It’s kind of trendy for retailers to start accepting bitcoin at the moment. Services like Coinbase are making it easier for them to do so, and it provides good publicity, as the cryptocurrency remains outside the mainstream. But that’s not to say it’s just a stunt – Dell opened up to bitcoin payments last month, and on the weekend founder Michael Dell tweeted that someone had put in a server order for 85 bitcoin, or around $50,000. Not bad for physical servers (renting the virtual kind with bitcoin is old hat.) Retailer Overstock said in March that it had taken $1 million in bitcoin payments in just two months.
