Watch the whole video till the end. Love the quote near the end. Which somewhat agree on it. Drop is necessary for us to take a step back and evaluate the currency.

Similar with the stock market, when a company drop. Something went wrong somewhere. Not just us as investor, but business owner and developers as well to evaluate and maybe to even change the business model.

As a developer and entrepreneur myself, trend do change over the time as well. The key to survival is to able to adapt to changes. Which is a better approach than blind faith hoping things to rebounds.
