Bitcoin Falls Below $5,000 For First Time Since October 2017 (bbc.com)

The value of Bitcoin has hit a new low of $4,951, bringing the total value of all Bitcoin in existence to below $87 billion. Much of the turmoil can be attributed to the split of Bitcoin Cash on November 15th. The Bitcoin offshoot has been split into two different cryptocurrencies, which are now in competition with each other. The BBC reports: Bitcoin exchange Kraken said in a blog post that it regarded one of the two new Bitcoin Cash crypto-currencies -- Bitcoin SV -- as "an extremely risky investment." At its peak, in November 2017, it briefly hit $19,783 - which means the price has fallen by about 75%. After the excitements of last year when the price soared to nearly $20,000 and then tumbled, Bitcoin has been rather dull and stable for much of 2018, settling between $6,000 and $7,000.

      These days "valuables" are mostly journal entries in a purely digital world, and the governments have the borders locked down tight.

      Bitcoin uses SHA-256(SHA-256(nonce+data)) < target value. They don't actually look for collisions.

      And if they did look for collisions, at the peak hash rate thus far achieved (about 2^69 hashes per second) it would still take about 2^161 years to reach a 50% probability of finding one. This would make BTC transactions a bit slower than they are now.

      Seems like an immensely risky scheme for a problem they could solve with a few billion dollars. In fact it would be odd if they hadn't spent a few billion on supercomputers that are able to brute force hashes and do massive dictionary attacks against AES etc.

      Aside from anything else they couldn't really use it to brute force anything really interesting, because the public nature of the system would mean that other intelligence agencies would immediately know what they were doing. Plus the way Bitcoin works the amount of computing power this would generate is so small and so slow to muster it would be impractical.

    FTFA: "At its peak, in November 2017, it (Bitcoin Cash) briefly hit $19,783 - which means the price has fallen by about 75%." The author of the story is inconsistently referring to BTC and BCH. BCH has NEVER gotten anywhere close to $19k, BTC has. There are other places in the short summary where I had to stop and think if the author was referring to BTC or BCH.

    The speculative value of BTC was based in its limited supply. Forking the coin doubles the mineable money supply, so the speculative value has to drop by half to adjust for this, besides kicking off a whole new race to waste energy mining the new coin.

    But there is value in a fiat currency. Currency is much like shares in a company, except the company is the country that issues the currency. Now granted, the country can issue more currency, and your share can get smaller, but fiat currencies very much do have intrinsic value. Unless you think the US economy is worth nothing, of course, which is pretty self-evident that it's not the case.

    Bitcoin (and other "cash" cryptocurrencies not tied to an asset or a fiat currency), on the other hand, is a share in literally nothing. ICOs are de-facto shares in the respective companies, but the market is so poorly regulated you'd have to be a total idiot to invest in one.
