because every single btc you got have its corresponding value in your local fiat so just keep collecting and save for more.
You are right. Collecting and saving your bitcoins are in the same vein as collecting your money. Both may be used for emergency purposes or for paying your daily/monthly obligations but the difference lies on its nature. Since money has been around ever since, it has been accepted as the main medium of exchange around the world. Most of the people in the world know that their properties or services are always convertible to cash through payment. On the other hand, bitcoin being digital, hinders its growth especially to the developing countries that has limited access to the internet.
It is inevitable for the world to experience technological advancement and soon, most countries will adapt to the changes with regards to payment. Should bitcoin still exist in the far future, then it definitely has the potential in becoming an alternative to fiat soon.
