Lucy decided to do Bitcoin mining after taking a FinTech course at UCI. The cost to buy a mining machine is $1600 and she needs 50 of them. A large cost is from electricity, which is estimated to be $ 34,000 per year in California. She is confident that she can win 1 block in 3 years. Note that the block reward is 6.25 BTC now and assume that stays the same during this period. In addition, there will be a fee of 0.00006 BTC per transaction that she will get. On average, each block contains 2500 transactions. The BTC price is $29,500
