Psst. You can use Bitcoin for whatever purpose you may see fit. You want to use it as an investment? A payment currency? A way of having real ownership over your money? A way of hiding your wealth from the government? You may even use it to buy those anime waifu pillows or Belle Delphine's bath water and I don't care one bit. Because that's the point! You have complete freedom with Bitcoin, and you don't need to care what people think!
I couldn't agree more.
No matter how we use Bitcoin, it is still going to the point where its price is going again near zero, its going to be devalued, because another cryptocurrency is going to replace it, but we're too far from that. Bitcoin is just dying in OPs world, but never in the majority of us. Spending it wherever you like doesn't matter, because it was made that way, to be a digital currency that can be pay on any goods or services, and that's what happening now.
