Making various transactions, either for goods or services is part of the activities of individuals and households. Obviously the utilization of the flexibility of Bitcoin for these transactions is on the rise, but something we're yet to experience, is using Bitcoin for micro transactions; gaming, online tipping, unlock assets of content creation, just to mention a few. For flat currencies, smaller units of the currencies may be in short supply to make such transactions. Households and individuals will surely be jumping at the prospect of the option of Bitcoin for these nature of transactions.
The reality of using BTC for micro transactions is already here and it is all thanks to second layer solutions like the lightning network that has been developed and improved overtime.
Although there would be a need for further innovation and upgrade on the lightning network, the real issue here, will be that more Blockchain companies should aim to develop and create more user-friendly decentralized Blockchain applications so as there would be wide spread adoption and use of Bitcoin for even the slightest merger transactions around the world.
