How Mining of Bitcoins Works ? Mao Lal
What is Bitcoin? • An open source P2P digital currency • Bitcoin is a digital currency, a protocol, and a software that enables • Instant peer-to-peer transactions; Worldwide payments • Irreversible by design; Almost no processing fee • Relies on cryptography and p2p network – no central authority • 21 million Bitcoins issued over 100+ years • 11 million issued to date, worth > $1 bn, 10%+ changing hands monthly
Setting up to use Bitcoins • Step 1 – get a Bitcoin Wallet • Step 2 – create your Bitcoin Address • Step 3 –Set up a Bitcoin Miner • Step 4 – join a mining pool • Step 5 – Give up and buy some coins, or look to Alt Coins ;) • Step 6 – Don’t just hoard the coins, use them in commerce or at least sell them to mitigate price risk
Mining • Note – most Bitcoin users don’t mine. It is a competitive and fast moving business • Initially – CPU in your PC • Rapidly moved to AMD GPUs for 50-100x gain • 600 mh/s, 300w power • Development of FPGA devices • 800 mh/s, 60w, power costs becoming important • Development of ASIC – 100x increase • 60+ gh/s, 400w
Mining Equipment • Started with the nice idea of a ‘gaming rig’ that would pay for itself; something like:
Mining Equipment • But I was a year late and a Dollar short – This was the average rig by the time I started
Mining Equipment • BFL – FPGA to the rescue • $500 to buy • $10 per day income • 60 watts • 832 mh/s • 50-25 Coin payout drop ☹
Alt Coins • Litecoins with a Gaming Rig • 3 x 7950 GPU • 1000 watts • Very hot • $2-3 per day ☹
USB - ASIC • The same power as a high end graphics card • Same price • But 5 watts vs 300+ • $1 per day • No payback • But no heat!
AVALON - ASIC • ASIC is here • 66 gh/s • 750 watts • $1500 • 10 day ROI • Now £100 pd
The Beast 3 x 80 gh/s ● 35 degrees + ● 3 kw ● Equiv to 250 GPUs ●
Mining Difficulty – SkyNet ??? • +20% per 12 days, 225 TH/s or c 1m GPUs
Mining Conclusions • Too late to get into Bitcoin mining due to: • Difficulty rising 1.5% per day • ASIC miner rigs the only viable option • 3 month delays to get an ASIC miner • Other options for mining: • CPU – Try PrimeCoin • GPUs - Litecoin – the Silver to Bitcoin’s gold
Trading • B$ made the news due to extreme price rises and crashes • Due to day traders getting interested
Trading • Lots of online ‘Bureau De Change’ to swap $/£ to B$ • MtGox.com, Cryptsy.com, BTC-e.com • Slow, KYC, fees, but works
