#Bitcoin was born and meant to be digital money.

Money is whatever you use as a “proxy” to exchange goods. Thus, everything can be money. Different type of money have different characteristics, like scarcity, durability and salability.

As of today, Bitcoin is the best form of money ever invented.

When you see it as an “investment” you are probably (just hypothetically) looking at it as “I want more dollars/euros/whatever”. When Bitcoin is money, then yes, the bitcoin you stack becomes saving.

Why saving in Bitcoin and not in dollars?

Because dollars are programmed to lose their value over time, thus making it a bad saving mean. Bitcoin, on the other hand, is programmed to keep its value over time (actually increasing your purchasing power), making it the best saving technology ever invented.

Does it make sense? Does it answer to your question?
