Expensive is relative to everyone - but people who say bitcoin is expensive are basically orienting themselves and comparing its price between then and now. In 2019 - someone with $4K could buy more than 1 btc - but now, $4K can only buy 0.041 btc. Maybe that's why many of them say bitcoin is expensive - they are always oriented towards past prices. But anyone who has money can always buy and accumulate regardless of how many satoshis they can buy with their money now. The point is only one - bitcoin can always be bought and not everyone will consider it too late.
Some people only focus on the past. In the past, the price of Bitcoin was very low, now at $95k, they think that Bitcoin is expensive. Can't those ignorant people focus on the future? Will the price of Bitcoin not be higher in the future? Of course the price of Bitcoin will be much higher in the future. We only think negative that Bitcoin is expensive, we should think positive. A limited supply of Bitcoin, which will no longer increase in the future, will increase popularity and demand, which will make the price of Bitcoin even higher. For those who think bitcoin is expensive now, I don't know what they will think when it hits 1 million.
