I've felt much the same. The argument is always that the "algorithm holds the value" but in practice we see that the value is based on a "market" of supply and demand. The demand comes from new investors mainly, which is the main feature of a ponzi scheme. The markets are far more susceptible to pump and dump schemes than any other market that I'm aware (not an expert). I agree that gold/ silver is far superior, and the fraud in those markets being exposed would be way more significant than cryptos.
