Update README.md

[svpn]

Minor error in text.

Hmmm. I somehow can't see the change. Would you mind pointing it out? Also, this needs to be rebased.

Thanks.

In the old text, the word "on" is repeated twice: "relies on on the Satoshi"

Rebase isn't needed; a manual resolve should work fine for this.
