We all know the cycle, it is always happening in the same way. Although the pattern may be not 100% the same, but it looks like to happen almost the same as in the previous cycle. But of course, there will be always a chance of any surprise. The price change of crypto coins can be very unpredictable.
The market indeed is very unpredictable and it would be very dangerous to even attempt to predict it, especially in the short-term. Its true that bitcoin's past performance may not always guarantee its future results, but just like you've rightly stated, Bitcoin has a pattern that it has maintained over the years and there's also a huge possibility of maintaining the same pattern in the long run, so these patterns may not actually be the same because there are lots of factors that influences the price movement of bitcoin and most of these factors are often based on real life events so these are not things that are easy for anyone to predict, for example there could be a bomb blast in the White House in Washington DC and such an event may have its impact on the crypto market depending on how the news influences the market or how investors react to such a news,these sort of things aren't what we can predict but when they happen, they may have a huge impact on bitcoin.
So these previous patterns is only there to give investors a clue of how to approach the market, and one of those patterns includes bitcoin's potential for long-term growth, this has always been how it is, and it has maintained this pattern till date.
