Hasn't volatility been affecting price ever since people started assigning monetary value to Bitcoin? I mean, we're talking about 5,000 BTC for Pizza to now 30,000,000 dollars in less than 10 years. So it's not just about years, it's just periods in between, of course the value rises and falls again and again. That's how markets work, duh?
Only I think there is a big difference between Bitcoin market and, say, stock market. Are there examples of companies that survived a 80% decline? I don't think there are many of them, and even if we can find one or two they are exceptions from the main rule. In the crypto market, however, there are many of such examples. I think that shows that Bitcoin is a very strong asset, and thus we have all the reasons to believe that BTC will surpass its ATH again in the future.
