Bitcoin and cryptocurrencies did have a great run, although manipulation claims have emerged:

There are many, many supportive factors for the new technology embodied in bitcoins, but here are 3 (there are more):

  1. Cryptos are designed to enhance freedom - to be stateless and free of 'leadership'
  2. To be not subject to single points of failure - distributed
  3. To shrug off government control

But ... on all of those three there are clear failures.

On 1. Around 40% of bitcoins is held by a small group of users, around 1000 of them

  • This concentration makes it potentially more open to manipulation
  • These big (and in context of the BTC market size, huge) players can move the market by their buy or sell actions

2. Failure ... I dunno about anyone else but I've lost counts of the number of failed exhanges, hacks of wallets, thieving ....

3. 'No government control' - yeah right, tell that to the South Korean government (and China) - statements from them are having a huge impact on the price.

Comments welcome
