Faster transactions is just one side of the story, and privacy is another part.
Imagine, I have more than 10m USD and I want to donate some money for the fight against Covid-19. here if I donate a huge amount of money, everyone(Including government) will start tracking my backing account and transactions. But, in the crypto world you won't have such problem and you can donate without of drama and being worry about your privacy.
Actually, I wanted to run a crypto accepted donation campaign against Covid-19 in order to buy some free masks and gloves for the homeless people. Because they are the most vulnerable part the world and the virus can speared by them much easier than everyone can think of it.
