I suppose the main point of this thread is:

If it ever came to it, we supporters of Bitcoin should not support the government doing away with physical cash, nor should we see cash as a threat to crypto. Further, any crypto that uses bank-like principals and is supported by a central bank, should also not be supported by this community.

The main reason for both, at least as far as this thread is concerned, is negative interest rates. There's good reason to believe this is not just fanatical talk. If you really believe the Fed doesn't have a choice but to continue expanding the Money Supply, or believe they'd fall back in recession if they did really stop the expansion. Then the truth is even if they stop, they'll just  begin anew. If we also acknowledge government debt is growing out of control. There's reason to believe the government may need to obtain additional money quickly. Capital controls have already been used in other countries, now negative interest rates are being used. Are we asking why? Regardless of the answer, there's away around each - crypto and cash. One can be banned by country law, the other done away with in the name of "progress". Just a word of warning is all.
