When we look at Bitcoin, we see a resource with a limited supply which cannot be obtained by any other means than mining it. Very similar to gold. In our history gold was first used as a direct means of payment - as ‘currency’. Together with gold there was silver which had similar properties but which was a bit less rare to find. After some time in which coins were made out of silver and gold there came the time of paper money.

What was holding me back from using pgp for a very long time was the fear of loosing my private keys and then not to be able to decode any messages sent to me. Also I didn’t feel comfortable storing a backup of my private keys in any place where they might easily be stolen. tl;dr pipe your private key through paperkey to dmtx and print a data matrix (QR-code) on paper

tl;dr For a buy and hold strategy for any kind of crypto I suggest to allocate a budget for every month and every week to buy for the same amount. At any time in history, humans seem to over or underestimate the value of pretty much everything - that’s why there is so much volatility in the markets (stocks, crypto and other ressources). If we look a litte bit deeper its not so much that we get it right and wrong at the same time, it’s rather that the same resource has a different value to different people at the same time.
