In all honesty, bitcoin as a currency won't be happening soon in the near future. Given the current circumstance of cryptocurrencies and its regulations, not all countries allow its circulation and usage. In addition, its decentralized nature makes its value very volatile compared to fiat, which is relatively stable. Lastly, its limited number of supply in the market makes its value inflationary in the future.
I do not see bitcoin replacing the conventional fiat soon but its role as an alternative currency fits in that role perfectly.
^ We are just the same, due to the fact that bitcoin has a limited supply and it could be possible for us to make this as a fiat replacement. People think about the value of the bitcoin, they will keep this and let their bitcoin sleep on their wallet and sell when they saw that the price was in the moon at price. Bitcoin is a store value, that could make profit via 2x or even 5x from your initial capital. Due to the limited supply people are now hoarding after accumulating bitcoin in the lowest price.
