It isn't that easy to make people to use bitcoin similar to currency. For the same what we need is more marketplace to accept bitcoin as well other digital currencies. Right now only very few online Marketplaces have been accepting bitcoin into their businesses. Day to day usage need to increase only then it can get be sure to be same as currency.
Agree. Without merchant acceptance, people won't have a reason to use Bitcoin at all. I believe that the main issue with Bitcoin is the volatility in price. A currency needs to be as stable as possible for people to trust it. Bitcoin lacks stability, which renders it useless for business use. Not to mention, transaction speed is slow, and fees are high. To get people into using Bitcoin as a currency, there needs to be a solution to the mentioned flaws.
Hopefully, with the Lightning Network, we could attract more people into using Bitcoin for their daily lives. The benefits are numerous such as instant transactions, and cheap fees. However, for volatility to be solved, there needs to be proper regulatory measures across cryptocurrency exchanges. Only then, Bitcoin will be comparable to a traditional currency or Gold, whose value isn't extremely volatile within short periods of time.
Nonetheless, the more we spread the word about Bitcoin, the better as people will become curious into using cryptocurrencies on top of existing fiat currencies. Just my opinion
