Transaction costs are basically the money that is paid to someone for doing the bookkeeping work of transferring your dollars or Bitcoins or whatever to someone else, subtracting them from your account and adding them to the recipient's account and making sure everyone's records are up to date.In any sort of electronic payment system -- for dollars or Bitcoins or whatever -- someone needs to do that work, since if they didn't I could just go around being like "oh yeah I have a million Bitcoins [dollars], give me all your heroin" and no one would know if I was lying.And if you want someone to do that work I guess someone else needs to pay them.If you want to send $1,000 via Western Union, Western Union (and some banks) does that work, and charges you a fee.You type in what you want to send and Western Union tells you that you'll pay a fee of $5 or $20 or $95, and you keenly feel Western Union sticking its hand in your pocket.If you want to buy something online with your Visa card for $1,000, Visa (and some banks) does that work, but it doesn't explicitly charge you a fee.

You just pay $1,000: Visa's fees (call them 2 or 3 percent) are paid by the merchant so you don't see them directly.The merchant does, and complains, but mostly out of your earshot.This counts as financial innovation: Visa, founded in 1958, is stealthier than Western Union, founded in 1851.Bitcoin is quite a bit better yet: If you buy something using Bitcoins, neither the buyer nor the seller normally pays any transaction fees.bitcoin miner on linuxInstead, the transaction is processed by the network of Bitcoin miners, who do the work of confirming transactions -- plus some extra cryptographic makework!copy bitcoin blockchain-- in exchange for some Bitcoins.bitcoin president arrestedBasically every 10 minutes someone gets paid 25 Bitcoins for doing that work.drop in litecoin price

(Here is a good explainer.)Those Bitcoins come from ... the ground?the lingo is that they are "mined" ... so nobody "pays" them.The thing is though that they're kind of a lot.Here's a chart of how much they are: As of today miners took home about 3.5 percent of the value of transactions that they processed.litecoin guideWhich is more than credit card companies!bitcoin svenska kronorThough maybe less than Western Union, I don't know.Now there are some important differences between this mining profit and credit card transaction fees.ganar bitcoin 2014One is that this isn't a transaction fee, in that it isn't paid by the buyers or sellers.bitcoin mining hacker newsWhich is true; it's paid by the users of Bitcoin generally, I guess.bitcoin exchange in greece

It's like if you could pay with your Visa card, and it didn't cost you anything, and it didn't cost the merchant anything either, but at the end of the year the Federal Reserve printed $500 billion and handed it to Visa.That would compensate Visa for running a payments system, and the incidence of that cost would be on, like, "users of the dollar system," though it wouldn't be tied to transactions exactly.You'd bear that cost whether you used or hoarded your dollars.That's certainly true of Bitcoin, too.Presumably you use Bitcoins because you want to transact in them but hahahaha we all know that's not true.The second is that this isn't a transaction fee, in that it's not paid to miners to process transactions.It's paid to miners for mining.Put another way, the miners are mainly paid for their cryptographic makework, not really for processing transactions, which is computationally a trivial side effect of what they do with their fancy computers in Iceland.Put another 'nother way, this cost is "seignorage," not a transaction fee.

I do not find these responses very interesting but you might.The "mining" is not in itself a valuable activity.The reason miners are part of the Bitcoin ecosystem is to reward them for confirming that transactions are valid.That is the service they provide, so it stands to reason that that is what is being rewarded with their 3.5 percent profit.The third is that this fee is high only because of the relatively low volume of Bitcoin transactions, and will eventually get much lower.(See the prior point, it doesn't actually cost the miners much to do the transaction-processing work.)And, sure, as a percentage it's come down; in 2009, daily miners' revenues were frequently several thousand percent of daily transaction volumes.On the other hand, that trend is not obviously continuing; see that graph above.And here is the dollar cost of a Bitcoin transaction over time: Which does not quite tell the story of "mining transaction price will come down over time."But, I don't know, like I said I'm not much of a Bitcoin connoisseur.
