It's inarguable that BTC value has grown immensely overtime and it's one reason to keep accumulating BTC as you can. Apple has just unveiled iPhone 15 which is estimated to cost about 0.031 BTC with the current price. Comparing the price of previous iPhone to bitcoin, you'll see the important of investing in bitcoin than buying assets that depreciate in value overtime. Of course, the risk of investing in bitcoin can not be overlooked just like any other investment but the bitcoin risk is worth taking.

Previously I had never compared the value of Bitcoin with any device, including devices like the iPhone. But when you reviewed this here, I was also surprised that in 2021 you only needed 0.018 BTC if you wanted to get an iPhone 13, which in that year was the highest series for the iPhone. So there is a slight difference between the price of an iPhone in 2021 and the price of an iPhone this year with a different series, but this is only due to the influence of the current value or price of Bitcoin.This image below was taking from Coingecko comparing BTC needed to buy iPhone over the years.

Imagine holding the BTC that you used to buy iPhone 4s till the present day and see the number of iPhone 15 you can acquire with it. If you have not started investing in bitcoin, this is the right time to start.
It does look amazing, but it feels very boring to keep updating a device like the iPhone every year, even though in each series there are slight updates to the features and specs in it. And it is possible that next year there will also be differences again when the price of Bitcoin starts to increase because it will continue to be adjusted to the value in Bitcoin.
