No one is saying don't have patience (and expect instant gains within days). In fact, to emphasize this, I encourage everyone to look at haejin's predictions from several months ago.
Now, don't compare them to just $USD or other fiat. It's going to look great, because cryptos as a market have done extremely well. Compare them to just holding Bitcoin, or Ethereum, or whatever your "safe" and "uneducated" holding position would have been.
100-200% doesn't seem so great when you realize you could have made the same or more using a simple "buy the index fund" type mentality.
Those who just blindly emphasize "trust" and "patience" without looking at simple statistical analysis of predictions will likely be disappointed when the market no longer keeps going up up up.
