05:47 – There has been a lot of ICOs (Initial Coin Offering) lately and there has been opinions around them
06:03 – Bitcoin was always meant for virtual currency
- 06:09 – While Etherium has a virtual currency too called ether, its actual purpose is to be an open source platform to build decentralized applications or Dapps
- 06:22 – People now create simple Dapps issuing a token on the Ethereum blockchain to fund Dapps projects
- 06:32 – People thought DAO was an ICO but it wasn’t
- 06:35 – DAO has collected a hundred million dollars in ether
- 06:44 – After that, many ICOs have gone out
07:40 – There are only a few hundred people who send ether into their contract
08:11 – There was an article Nathan had read regarding Bitcoin’s current problem

3 Key Points:

Some startups are coming out as an ICO to fund themselves, but not all of them are legal.
Cryptocurrency still isn’t very stable so as a business owner, paying your people with this currency isn’t efficient.
Public blockchains are not scaling and there’s a protocol that needs to be followed.
