I definitely agree that the elimination of cash will result in massive state surveillance. I do not think, as some others do, that Bitcoin is a kind of revolution against the powers that be in and of itself. It is, however, superior to fiat currency in that it cannot be printed endlessly, making it a more sound store of value. As for the privacy aspect, coins like Monero and Bytecoin are entirely different from the openly readable ledger system of Bitcoin, etc.

So far, crypto has helped me to help others with no middle man or state in between. I like this. You are right, though, the state will co-opt and crack down. Like any technology, it can be used for good or ill. I like what you said about buying land and tangible wealth with your profits. This is the approach I am taking as well. Gold is always going to be gold, too, as far as we can see.

Thanks so much for the insightful comment.
