I think it depends on your intentions. If your intentions is to hide money yes it could be considered to be like a Swiss bank.
As far as being anonymous BTC is better in my mind at this point. Swiss accounts are not what they once were.
I think most reasons for a swiss account are possibly unethical. Bitcoin has good uses aswell.
So they could be the same just depends on your use.
People can hide money lots of different ways, cash, precious metals, put it into diamonds, etc. I dont like how the media makes btc out to be some sort of thing used primarily by criminals to hide money. If anything it a lot riskier to use btc to hide "black money" becasue some researchers have proven there are ways to track btc/wallets.
