Some people always think bitcoin is expensive but it is not. For instance if 1 bitcoin is = $10,000 we will say it is too expensive and when we look at the price in next two years it can be double($20,000-$30,000) and we realize that bitcoin at $10,000 was very cheap and something very affordable. The future will always make us understand that bitcoin is not expensive, we only miss expensive opportunities that we won't be able to get back.
Bitcoin is perceived as expensive relative to the previous price ($0.1, $1, $10, $100, $1000), but remains cheap relative to the future price ($100,000, $1,000,000). It is a misperception to evaluate the price of bitcoin relative to the price of past years, because it seems that it is too late to buy bitcoin. But this is not true at all. There will always be opportunities if you imagine the cost of bitcoin in the perspective of 10, 20 or more years, and then the current $10k or even $50k will turn out to be a sale with a discount.
Let go of the past. Focus on the future.
