Economy is strong.
I don't know in which universe you live, but apparently in a parallel one where things happen a little differently than where the rest of us live. We are in the midst of one of the biggest economic crises in the last 40 to 50 years, and on the brink of the biggest military conflict since the end of World War II.
We will know for sure that 19k is no longer possible only after the price gets much higher.
19k is something that will be broken many more times, regardless of the fact that from time to time (like now) the market prepares a small trap and tries to convince the naive that it's time for a new bull run. The biggest mistake that the OP and others have is that he is completely lost in time, and that's why he loses money. However, he doesn't have to be completely disappointed, because his loss is someone else's gain.
