Purchasing Bitcoin in this current price is not advisable to investors, because it will not help you to achieve what other investors that purchased Bitcoin when the price was low which is the season professional investors use to purchase Bitcoin and hold for bullish season to appear before they can release them for sale. If you are not expecting huge income from Bitcoin, you can purchase Bitcoin in this current price but it will not allow you to make a huge amount of income, because you purchase when the price of Bitcoin is high. No doubt about that if the price of Bitcoin will reach $100,000, because the price of Bitcoin is going to increase above $100,000 in this month and it will help those investors that are still waiting for the price to appear in this month of December before they can trade to increase their income.
I understand what you say, in itself you are right, it is advisable and what many should do, however we are going through a good BTC streak, we see that it has almost reached $ 100k and well, and yes it can very well go down, but let's say that instead of going down it can reach about $ 150k which is very likely, then we will have lost a tremendous opportunity, that's what I mean, however it is a risk that some or very few dare to take, that is what everyone has and can do according to their money, everything is in the capacity of each one, the best thing is to take advantage of opportunities when they arise, in the same way if you buy now and it goes down a lot, at any moment the btc will go up much more and you would already be winning.
