At some point we have to look away from the price and just go ahead and buy if you have the funds for a spear, as long as we have a long-term Bitcoin investment plan because even if you consider Bitcoin's current price as high it still will be a low price on the long run most especially when there is a market bull run.
Buying Bitcoin at its current price of 30k+ is not too high because we have institutional investors who still buy at a price higher than this and will still accumulate more without selling a bit even when their few buy prices are already in profits but since their already long term goal which is the most significant.
Bitcoin's ATH is twice its current levels, and Bitcoin always rises above previous peaks. Of course, it was more profitable to buy closer to the rate of 15 thousand, but even from today's value it is profitable to buy. Especially now, when large corporations and funds are increasingly investing in long-term investments in bitcoin. Of course, 21 million coins is not so little, but for 8 billion earthlings it will not be enough not only for a whole bitcoin, but also for a tenth of it. And large investors stock up at once in the thousands and tens of thousands, so there is even less left for individual people. And while we still have the opportunity to grab our piece of bitcoin.
