You can buy with it, I think you should check out purse.io and you will find a lot of stuffs that you can buy from there. You can also check out overstock.com, there are lots of things there too, but I wouldnt recommend overstock.com, I prefer purse.io, cause whatever youre buying there is coming from Amazon and youre also getting a percentage (about 25) off everything you buy. You can also get gift cards from BitPay. There are lots of ways you can spend your Bitcoin, I believe you can also make use of it on Expedia.
