Conclusions
We believe Bitcoin could become a major means of payment for e-commerce and
may emerge as a serious competitor to traditional money-transfer providers. As a
medium of exchange, Bitcoin has clear potential for growth, in our view.
There is much speculation that Bitcoin may help avoid high taxes, capital
controls, and confiscation. The correlation between CNY's share of volume of all
Bitcoin exchanges and price of Bitcoin is rising. That said, the fact that all Bitcoin
transactions are publically available and that every Bitcoin has a unique
transaction history that cannot be altered may ultimately limit its use in the black
market/underworld.
Bitcoin’s role as a store of value can compromise its viability as a medium of
exchange. Its high volatility, a result of speculative activities, is hindering its
general acceptance as a means of payments for on-line commerce.
Is Bitcoin a bubble? Assuming Bitcoin becomes (1) a major player in both ecommerce
and money transfer and (2) a significant store of value with a
reputation close to silver, our fair value analysis implies a maximum market
capitalization of Bitcoin of $15bn (1BTC = 1300 USD). This suggests that the 100
fold increase in Bitcoin prices this year is at risk of running ahead of its
fundamentals.
I think that, overall, it's an excellent assessment of near term investment risks.
