Bitcoin Process and Bitcoin Supply
Blocks
Transactions
• Openly broadcasted to network
• Unique digital signature
• Links with previous transactions
• 50K-70K transactions daily
Blocks Chain
• Determine the order of
transactions
• Answer unique math problem
• Built by pools of miners:
approximately 144 blocks/d per
day
• Now 25 bitcoins are released to
pool of miners for a solved block
• Consists of blocks referencing
each other (double spending
protection)
• Simultaneously solved blocks
build several branches
• Chain is switched to a longest
branch
• Attacking the system is not
economically viable
“Mining” is a competitive and decentralized process of spending computing power to process
transactions and secure the network by using specialized hardware and collecting new bitcoins in
exchange for this service.

Borrowing and Lending
62

Bitcoin Borrowing and Lending
FUNCTION
Provides an opportunity to borrow and lend bitcoins and earn interest on the
amount of loan
TYPES
Peer-to-Peer – allows a creditor to choose which loan to fund:
• Borrowers are graded by creditworthiness, which defines repayment parameters;
• Lenders browse loans listings to find ones meeting their investment criteria.
Bank-like Lending 1 – borrower or lender are not identified for each other:
• Deposit BTC to earn high interest rate;
• Borrow BTC from the platform in form of a loan.
REVENUE MODEL
Closing fees as percentage of loan amount;
Late payment fees and credit rating fees;
Interest rate spread.
RISKS
For peer-to-peer: site reputation heavily depends on borrowers quality;
For bank-like lending: ability to generate positive spread defines success of the
enterprise;
Volatility of BTC relatively to fiat can quickly wipe out the loan value for a lender.
1. The term is used unofficially to contrast these transactions to peer-to-peer alternative; the companies in this
group are explicitly not government-insured banks.

Bitcoin Borrowing and Lending: Conclusion
While Borrowing and Lending platforms represent a great
potential with Bitcoin credit card being a part of it, the site
owners release themselves of the liability for the loan

Release of the liability causes significant volume of discussion
about the platforms legitimacy and feasibility of the returns.

Bitcoin Ecosystem Map Methodology
• User adoption, defined by the site ranking and the time spent on the site per visit, affects a
company's success
• We assume that, aside from the differences in the bounce rate, the conversion rate of an engaged
user is approximately the same on all sites
• Bounce rate is the rate of people leaving the site after opening only one page
• Hence, we assume that the product of the site traffic and bounce rate allows comparing companies
in terms of number of paying users
• We assume that an average user performs same number of transactions and average transaction size
is the same for all the companies
• We assume that difference in the size of the fees and number of paying users allows comparing
companies for the revenue-generating potential
• High revenue potential does not mean, however, that a company is actually making money
75

Bitcoin Ecosystem: Conclusions
• While a necessary part of Bitcoin ecosystem, most of the wallets are provided for free. Coinbase,
positioning itself as a wallet, earns its money by converting BTC to USD;
• Benefitting on the large number of transactions, Bitcoin payment processors hold a strong position
in the value chain; downward pressure on fees from competition and establishment of new payment
networks for different cryptocurrencies (Ripple) can weaken the processors;
• While maintaining a loyal user base, Bitcoin exchanges seem to compete on price and new trading
opportunities, adding more instruments and currency pairs;
• Bitcoin mining hardware and ATMs experience sellers’ market; capped supply of BTC, however,
would not allow such imbalance to carry on for a long time;
• The main problem with the Bitcoin traded investment vehicles is the ability of a big player to affect
the Bitcoin price, hence, disrupting the forces of market supply and demand;
• A number of startups is receiving funding from prominent venture capital investors to grow services
within the Bitcoin ecosystem;
• Borrowing and lending in Bitcoin seems to be the space where a lot of new opportunities are being
created; the lack of legal protection, however, results in a great caution from the users;
• The Bitcoin vale chain is still in formation with the number of services are yet to come.
