Many early adopters intend to use bitcoin as a currency, and to hold it as a long term investment. Doing both at the same time means replenishing what you use as you go along. When I buy something online, I use bitcoin if I have the chance, but I prefer to deplete my USD savings rather than my bitcoin savings, so I do a quick USD -> btc -> purchase. If it's a miniscule amount then I might not bother with the USD -> bitcoin step, but if a bunch of miniscule purchases added up, then I would still eventually replete my bitcoin holdings.
Ok, here´s the thing i dont get. Why would anyone want to do that?
So you loose money on the exchange (fees), pay the transaction fee and dont get any fancy things like cash back you would get using a credit card. So, basicly you are paying a premium for being able to use bitcoin?
