As said before, you need to understand the economics. When a commodity supply is less and the demand to accumulate the commodity is high, the price goes up for that particular commodity in order to meet the demand. Just a classic example of supply and demand. Similar things happen with Bitcoins also. Hence, the price can definitely go till 1M if the demand to accumulate the coin keeps on increasing day by day.
There is always a possibility that this could happen, and you are right. That is a normal thing, because if there is an increase in demand, then the price will increase significantly, which will adjust to that demand. Likewise with what Bitcoin will experience, if demand continues and supply is always running low, then it is inevitable that the price will automatically increase, so reaching $1M could happen, but not in the near future.
There must be good news that can trigger an increase in the price of bitcoin, as happened last time when the Bitcoin ETF was launched and the Halving occurred, making many people think that the price of bitcoin would soar high and in fact the whales granted their wish. To reach the price of $1M will certainly not be as easy as we imagine, the whales have to burn a lot of money.
It is certain that any good news will trigger the movement of Bitcoin, as you say. As the the last is ETF's influence, and it is not impossible ETF Ethereum if it will happen, will also give back encouragement. I think the Whale did not affect it rose yesterday but indeed the trade was quite high, because of the influence of the ETF. I also think things that are not easy to reach $ 1M in the near future for Bitcoin can achieve it. It takes will take several times to halving Bitcoin again.
Well, whether good news or events will trigger Bitcoin or not, the $1m worth is too inflationary, I do not think this will ever happen. It will even further show the unseriousness of Bitcoin and cause more laughter on the cryptocurrency. Many of you might be looking at the value alone and what it can do for you but this value may not be a reasonable worth in the end. This may even be a reason why the government will now focus their beam on it again and find the means to compress it just like Gold in order to curb some excesses.
Have you ever wondered why Bitcoin is close to $70,000 with a market cap of almost $1.4T, while Gold is at around $2345 with a market capitalization of almost $16T, which is more than 10 times greater than the market capitalization of Bitcoin? The reason is what I mentioned, it is a compressed commodity asset and it happened because the government planned it well from the beginning so that it would not cause inflation and too-high economic disparity.
But who planned Bitcoin to be cautious this way? No one. People are just interested in the money to be made from it. Regardless, I do not think it can bless people to the point that 1BTC will now be worth $1m, at least, not in the next 10 decades.
