Quote from Hoi:
With the billions I meant the current market-cap of Bitcoin alone. I think that about 500,000 coins are lost, and still 11,500,000 BTC in circulation. Makes: 11,5 ml x 750 USD = 8.6 billion.
The BTC-network itself is about 7900 TeraHash. With an average price of 10 USD/GigaHash, it's about: 79 Million USD, which needs to be replaced each 6 months (in this crazy arms race).
You cannot re-tool to all Crypto's. There are two groups, each with their own hardware, which cannot be re-tooled anymore (technically or economically):
a) the SHA-256 crypto's. Like BTC, PPC, Namecoin.
b) the Scrypt crypto's: Like Litecoin, feathercoin, and a huge number of copycats.
For SHA-256 you need expensive ASIC-hardware.
For Scrypt you need PC's with several GPU's from AMD.
Professionals are on the ASIC's and BTC.
Hope it helps.....
Thanks for your response.
For the re-tooling, while what you say may be true for the actual mining process (reliant on specialized hardware towards the tail end that is heavily optimized for a particular hashing method), for the transaction networks themselves, it is not overly complex to accommodate multiple hashing methods (please correct me if I am wrong) and thus unlimited numbers of cryptocurrencies.
This is what I meant, as the mining is a process where, given BTC's design, the majority of the coins are discovered early on in the process, so the other considerations, such as the infrastructure itself for using the coin, is far more relevant in the long run. Mining is important for early adopters/hoarders/speculators.
The price itself is built purely on speculation, and there is still a discovery process going on with regard to the implications world-wide for BTC (and eventually, others) as a mechanism of commerce. Commodities either serve a practical purpose and/or are a store of value. Gold is inherently limited in that they ain't making any more of it (like land), but this is not the case with BTC.
So, imo, BTC will need to rely on other use cases to remain valuable, and what you said about the infrastructure will become far more relevant in time, similar to how email is popular because of the widespread adoption. This is why I bring up the point about generically built infrastructure applicable to a variety of cryptocurrencies (not the actual mining process itself). And, in my view, the actual value of BTC if it is only seen as a commodity and not a currency, can be heavily argued in both directions, thus speculation will likely run wild going forward until the true value is ascertained.
In short, BTC needs to provide unique value that cannot be easily copied, if it is not adopted as a currency.
These responses on Quora are interesting to read, detailing that BTC, in the eyes of China, is seen as a commodity, instead of a currency. Thus, speculation will likely remain very wild for quite some time:
