The further you move from the blockchain, the more opportunity for corruption

[Elwar]

The blockchain is math, it is why we like Bitcoin and believe it can be used to achieve great things.

But if you move away from the blockchain, you start introducing things other than math. You start adding things like trust, force, faith and you get the same system that Bitcoin was created to replace.

When a company takes bitcoins from the blockchain ledger and creates their own ledger, then you are putting faith into their ledger over a proven math based system.

When government says they are going to regulate bitcoin, they can only use force against things other than the math of the blockchain.

Invest and support those systems that are closest to the blockchain, avoid those that are furthest from it.
