Arbitrage - What it is and how it works Arbitrage refers to the process of instantly trading one or more pairs of currencies or odds for a nigh risk-free profit. Usually, this involves two exchanges (this is then called a two-legged arbitrage); although more are, of course, possible. There are several steps when executing an arbitrage: Find a suitable ...

Basically there are five main ways of getting bitcoins: Mining Buying Offering goods and services for Bitcoin Obtaining for free through micro payment Asking a friend who already has them to give a tiny fraction for free Let's start with mining: first of all I have to warn that currently there is almost impossible to mine by your own. You need to have a ...

Is there space for me on your team? I have spent most of this year trying to answer the same question, starting with the recognition that I could solve all the technical aspects (web programming, Bitcoin handling, trading engine, server security, etc.). Technically, you need a website and a trading engine that matches buyers and sellers. Whilst there are ...

A large investor might be trying to move the market. Sell walls create an impression of a strong supply. This makes some people, unwilling to wait for the wall to break down, pitch their sales offers below the wall. By moving the wall closer to the current bid again, a large investor might be able to move the market to a small extent and then buy at a lower ...

Shamelessly summarized from this extensive guide on local transactions: You want to meet in a sufficiently public location, such as a pub or mall, preferably one that has an open wifi. If you have agreed on terms in beforehand, print out what you agreed upon and take it with you. If you have not agreed on terms yet, be sure to check the current price of ...

Of course you may trade bitcoins with just anyone without having to pay fees to a centralized exchange. I think Bisq (formerly BitSquare) may be the best answer to the question; decentralized, free for some definitions of "free", and very low risk due to the escrow system - but not completely without fees, indeed as of 2017 one may end up paying quite much ...

I use this type of trading to accumulate buys at a cheaper price. Ex: if I spend 2 hours buying small amounts of coins so nobody notices the large buys, then I put up a large sell wall ($30k-$45k) to encourage sells. After that pushes down the market from panic sellers trying to under sell my wall, I instantly buy those sells up and remove my wall and then ...

Let's assume you're the outside observer. You see 1 BTC go from aaa to bbb, then from bbb to ccc, then from ccc to ddd, and them from ddd to zzz (zzz being associated with service Z). Can you see how easy it is to figure out that addresses aaa, bbb, ccc, and ddd belong to the same person? It doesn't even get much better if you split the money to different ...

No, you can transfer fractions of bitcoins easily. From the Myths section of the Wiki: One Bitcoin is divisible down to eight decimal places. There are really 2,099,999,997,690,000 (just over 2 quadrillion) maximum possible atomic units in the bitcoin system. The value of "1 BTC" represents 100,000,000 of these. In other words, each bitcoin is ...

Coming from a financial programming side (C++/Network/Trading experience), I would politely suggest that having a web team is not quite enough to make an exchange. Granted, your average Bitcoin exchange may not need the HFT credentials of your average dark pool or big name exchange. But you're still dealing with a system that needs high uptime, high ...

Essentially, you have to factor in 3 fees in a purchase: 1. Deposit fee (if applicable) This is usually a fee for wire transfers, and from my experience is only relevant if you deposit cash across economic zones, albeit this is slowly reducing to 'anywhere to asia', or outside of the SEPA zone. Kraken charges 5€ per wire transfer, SEPA transfers are free ...

How are fees charged? They are charged in the currency fee set during a trade. Due to a discreet nature of trade matching process, it's rather tricky to give a definite answer on how each individual fee is applied. However, a good rule of thumb is to choose a fee currency when placing an order, as this is the one in which fee will be subtracted. Are the ...

Mining was never supposed to be profitable. And it's a derivative of bitcoin which is already risky speculation. Don't add the extra, annoying risk-without-an-upside of wondering whether BFL will ship your machine in time to turn a profit. Even they state that there's no guarantee that their machines are profitable. If you are sure that the price of ...
