I've been into Bitcoin for quite a few years, and I'm impressed to see how far it has reached in the mainstream world. It's the most widely-adopted cryptocurrency for decentralized payments worldwide without the need for a middleman. In its current state, Bitcoin works wonders for ordinary people like you and me. It's only a matter of putting the right BTC address and the number of coins to send to get started using the Bitcoin blockchain.
However, my concern is how blind people are able to get used to Bitcoin? To my knowledge, wallets (either with a GUI or CLI) don't have "text-to-speech" features to make blind people's lives easier. It'd be great if developers keep blind people in mind to help increase the adoption of the pioneer cryptocurrency in the mainstream world. The only thing I've found is an audiobook of the Bitcoin whitepaper which is a great solution to introduce blind people into the "mechanics" of Bitcoin.
Any thoughts?

Bitcoin and other crypto currencies are not yet ready to serve everyone as it needs to solve first it's problems like what you have mentioned, blind people can't use bitcoin yet if it will implemented as the main payment system. That is only one of many problems that bitcoin will face in case it will be use as main payment someday.
If we are going to compare the fiat and bitcoin, fiat will be a lot simplier for blind people to use compare to bitcoin even if it can provide a mechanics that will convert speech to text and vice versa. But a solution will likely to be provided in the near future where everyone can easily use bitcoin and other currencies without any difficulties as we are continuing to develop our technology.
