we can see that bitcoin is now dropping, it touches 45000 dollars today but right now it is around $43000.

Long ago I stopped referring to BTC prices very much. Because it can make your comment obsolete in less than 2 hours. Just like it did today:

2+K move in 2 hours !

the price of pob has dropped a lot, and I can see some people getting angry because of the price,

Honestly, why would one be angry?
The only reason "why" I can see (and understand) - is if you are somehow preprogrammed "to buy high, and sell LOW"
Then, sure, when price drops, you must sell, and sell low, taking losses.
But why? WHY do you must to sell?

I am angry, when the prices from my buying orders surge, and I want to buy more, but price just surged too high, so I must stop buying.
This is exactly what happened to me and my POB buying activity 6-8 weeks ago.

Now, I AM HAPPY to see those low prices, so I can buy MOAR, with very little Hive spending.
So simple.
