If you compare the current price and the previous price, yes we can see that.
But if you go back to gold, it used to be trading at $10/gram and now it is trading at $169/gram, meaning the current price is high and the current price is cheap, as is the current price of Bitcoin.
I mean, you can't look at the current price of Bitcoin, if you want to buy, you have to calculate the price 5-10 years in the future, that's the buying and investing assumption, If the price of Bitcoin in the next 5 years jumps to the $200k level, of course you will say I bought cheap now, that's the market view.
Yeah, everything goes up, if we look at it as "is it too late" then we can't trade for anything because everything went up. Thanks to inflation the value of fiat keeps going down, and with some other stuff gets its own value, we have a double income that way. So bitcoin will get more value, while dollar will lose more value which means that price of bitcoin will keep on going higher and higher and there will not be any way to stop that and will keep going strong for good.
I understand why people may feel like they are too late because only 15 years ago it was few dollars and today it's 60k+ dollars so they feel like they are late, but it is not too late and you can still make a profit from bitcoin right now.
