There is digital Gold and it has existed shortly after the internet's payment systems gained recognition. I've used many of them and they are being used just as Bitcoin, but the only difference is that people do not know of this not to mention adopting it since developers and businesses do not look toward that angle due to Fiat's dominance. Bitcoin broke the jinx, contended with fiat and won, which makes it popular.
I doubt your saying.
If your saying is true, you were a gold investor or a gold trader many years ago. The Internet
blossomed in 1990s and maybe 'Digital Gold' trading started around it but what the hell is "Digital gold" in the past was used as same as Bitcoin. Your post has many things to doubt about your honesty in this post.
Additionally, it has a cap, meaning that there won't be unlimited gold, you can't print more gold, you have a limited amount of gold in the world and that's how it will stay and won't change at all, as long as you can't create gold out of something else thanks to some technological advancement, we have limited amount of gold and also bitcoin which makes them quite similar in that aspect too.
It's one of biggest attractive specifications of Bitcoin: a cap of its total supply, this is big different than gold and altcoins.
How is the 21M bitcoin cap defined and enforced?Equivalent network time is an interesting topic, that express Bitcoin controlled supply in effects of Bitcoin halving and required increasing time to mine a same 1
BTC with time.
Btw, can you explain me what is property and what is the asset?

Please don't care too much about calling term that is not important.
The importance with you, is if you have bitcoin, and you can hold it with a long time, you will be richer with bitcoin. Whatever term called by other people, is not important with you. It's not necessary to fall into argument, debate about it.
