But this is totally different from the initiative that provided potable water to a rural village in Nigeria. The latter is indeed an effort that has a huge impact on the lives of the people. It's a selfless undertaking.
This one with the bus is nothing more of an initiative to promote Bitcoin. It's either it was a form of gratitude for making money out of Bitcoin or a way to promote Bitcoin because the owner HODLs some and he/she wants others to also buy so that the price will rise and more profit is made, or both.
You're right, i also thought about it in such a way that some cam make a good charity out from it by giving out a free or subsidized transportation means to the people through their realize profits from bitcoin hodl, the main idea is just in giving back to the society through what bitcoin has impacted in you either collectively or individually, the bus is a display of fortune indeed derived out of bitcoin by the person involved and he's trying to pass a message through by writing bitcoin allover the bus, this could be that bitcoin is an alternative to economy sustainability.
There is a growing number of individuals who knows Bitcoin already as it was too hot and more ads to pop up on the internet and social media. This initiative made locally but is has a global impact. But it was not the most needed for all of us, what we need is the support of the government and allow everyone to participate in this and make use of this in the local areas by encouraging establishments to offer payment options that accept Bitcoin. Not in a way of spreading news regarding banning Bitcoin and capturing those who hold it.
i got your interesting points here, if one or two governments can give a start as El-Savador and Central African Republic, then let's give it a time, this will definitely be achieved soon, by then governments will have no option than to comply with the advance system of digital decentralized currency called bitcoin and realized their mistakes with CBDC.
