Panic could happen at any time in bitcoin world, we are going to live through panic probably a hundred times in the next 10 years, that is just a natural part of bitcoin world and that is not something we can stop. People just see the price go down a bit and suddenly they all start selling their coins. I would say that panic is not a problem and I think the smartest decision would be and that is why there is no need to get angst about all the potential panic that will happen in the future.
The price of the crypto (decentralized coins) are volatile but it doesn't need it will cause a panic every time it will dropped, over time as adoption increase, I believe people will be smarter and they'll mature, so they will understand the nature of the market and they will know how to handle themselves and make the right decision.
Just focus on what we can do during those panic times and you would actually make a profit. If you see price going down 50% lower or anything similar (anything under 30% would be fine) and you could just buy up as much as you can and in the end you will just wait for it to go back up and make a ton of profit.
Like I said, if they'll mature, they would do the right thing, so most probably that 50% dropped would not happen most of the time, it could be a rare occasion only.
