Of course it is, you need to do some research on numbers and do some thinking. People said that 1 BTC was the standard already during the previous ATH of $20k and look where we are now? That would be already 0.25 BTC is the old 1 BTC.
you are just doing numbers gymnastics by comparing how much a set amount of fiat could get you then vs now to say 0.25BTC is the old 1BTC. but 1 bitcoin is always going to be 1 bitcoin, what really changes is the fiat value.If you believe Bitcoin will stay undervalued like this forever you are in for a surprise. 
never said that.Very few people will manage to own 0.01 BTC and even fewer 0.1 BTC. 0.01 BTC is already worth more than $1000 and with this value it excludes most of the humans on the world from owning this amount as they can't afford to invest $1000 in anything.
that's obv. just from a supply POV there will only be 21 million bitcoins (~3.5 million already estimated to be lost), and we have 8 billion people on earth.
