Basically, the possibility of Bitcoin getting ATH is very big. We know that the halving years made Bitcoin mining even more difficult. And we know that mining costs are not small. I am sure that going forward, with Bitcoin being difficult to mine, it will make changes to the interest and price of BTC.
But, don't easily believe this theory. Because everyone has a different view.

One point is that particular halving, the difficulty of getting bitcoin from the mining industry.
While it's difficult to mine with more people start to gain interest, there's positive reactions that will take.
And yes, don't take any words but instead deal with your research and decide base from how you understand the potentials.
Mining difficulty will keep on popping up, but one who can afford to make a big farm and generate the highest hash can generate/mine good sum of cryptocurrencies yielding good revenue. As far concerned compared to the days of bitcoin reaching the peak, now we've got high number of people getting into mining. Halving and the entry of more people into mining too increase the difficulty for small mining farms.
