The connection is that with bitcoin, there is absolutely no worry about where the coins are and who has what. Its in the ledger that anyone can see. The issue brought up with regards to Monero I found as very interesting. Since privacy works both ways, as the article said, there is no way to verify that the Monero people are buying the exchange actually has. Once again, with BTC, once its off the exchange, the coins are yours. And that takes a huge network to protect.
Imagine you owning something precious to you. You can put it in your sock drawer and leave your front door unlocked... highly risky. You can live in a condo with restricted elevator access to each floor... a little more secure. You can live in a gated community, even better. You can put it in your safety deposit box at a bank, which is better still. But even then, the bank manager can easily confiscate it. You can get armed guards to protect your house, and now a robber probably would need a sophisticated plan to execute the theft. With each additional layer of protection, it takes more resources to get at it. Bitcoin is now at a level where no private individual, no corporation and no government can attack the network. Whatever level of energy that takes I am happy with. It dissuades anyone from wasting resources to attack it.
