Cause it's the time to humble the riches and en-riches the strong minder holders are winners in this space
What do you think will help to help boost the mindset of investors again after all the ordeal?
First, I think that you should improve your English.
Second, the majority of the BTC investors are just ordinary people, who bought a small amount of BTC with a part of their small savings.
It's OK for them to panic and sell, when the market gets stuck in a bear trend or the price drops fast. You can't have winners on the market without having losers. If everyone was winning nobody would be losing and the profits would be close to zero.
I don't think that anything will "boost the mindset" of such investors. If they don't believe in the future of BTC, just let them leave the market.
I'm still positive that a Bitcoin bull market will come somewhere around 2024.
