While I agree with your frustrations, I don't agree with your rational. If you look back at 2012-2014 on bitcoin you will see that it did indeed take over a year for prices to ultimately make a new high after about a 90% correction, but it did eventually make a new high.
The reason it is important to have good news even while price is declining is because it tells us that the infrastructure is being built. These aren't going away. The genie is out of the bottle at this point. Prices got over heated in December of 2017 and they have been mostly in correction mode ever since. At some point we run out of sellers and the price goes back up. As long as the infrastructure is continuing to improve it is just a waiting game until that happens.
