The rise in purchasing power of Bitcoin **with respect to the Euro**. lol, right! That's my whole point.

You're just making an argument about sound money vs fiat bullshit. If that's your only point, we simply agree. But you've somehow taken that point and wrapped it in a false argument about lending. Either you are making an argument about lending itself (in which case you should pick a single monetary context and stay within it), or you are merely re-stating the sound money thesis in an irrelevant costume (lending).
