even after all these years people that are not blind also cant use bitcoin 100% correct . this evolution takes time to be fit in normal ways first.and after everything get normal and work normal (for example paying a coffe with crypto or buying milk with crypto wallet) then this tech can get upgrade and go to other step to be usable for everyone .first step is to everyone use crypto in all around the world then new project and solutions will come to be useful for blind people also. 

Check out this project that goes over the wallet part: https://icywallet.com/ with a combination of ADA tools like screen readers they could visit an exchange's website to buy or trade coins. There are guidelines like WCAG here: https://www.w3.org/WAI/WCAG21/quickref/ that go over accessibility. I'm unaware of any exchanges are trading platforms that have incorporated this into their offerings, maybe someone else can chime in here.

Let alone for new innovations like this, facilities and other general services are still not optimal in providing services to people with disabilities. Of course, if there are developers who care about this it will surely give equal opportunities to disabled people to enjoy Crypto world. Although difficult, it does not mean impossible.

Well, the real problem for blind people is the Accessibility from a blind person perspective that he could see his Blockchain wallet more clearly and using the screen reader platform that lets you hear the words into audio so you can surely know how to transact and how many Bitcoin you had and so many other option but this is not enough because there are other features that are not really audible for this kind o application including the multiple sending to other Bitcoin address, it is still pretty hard for them to see it clearly,

Well this is the story of Craig McGee a blind that has Mine Bitcoin from his home however it is really not easy being a visual compared but thanks to the Braille project McGee has a chance in seeing more clearly read this ARTICLE and yes maybe this is the same as the IcyWallet SeaBits had mention because this Article is dated from Oct, 25 2017,

So I think there is already a project for the Blind to also engage with Bitcoin transaction without any problem.

It was great for the blind people having some opportunity here in crypto but believing that there are difficulties when performing this one unlike if you are just a one-yed person or crippled one. I can't a tool that could help them to function as normal traders or investors. These all possible with the help of other people who can guide them, not by doing it alone.

Not all blind people live alone, and there are different levels of blindness:

20/30 to 20/60 : is considered mild vision loss, or near-normal vision
20/70 to 20/160 : is considered moderate visual impairment, or moderate low vision
20/200 to 20/400 : is considered severe visual impairment, or severe low vision
20/500 to 20/1,000 : is considered profound visual impairment, or profound low vision
More than 20/1,000 : is considered near-total visual impairment, or near total blindness
No light perception (NLP) : is considered total visual impairment, or total blindness

Those that can see with some visual impairment would have a better chance to use the technology than those with NLP. People that fall into the NLP category could have a caretaker, friends or family who has introduced them to bitcoin. This would simplify some of these processes if done properly and hopefully with trust. According to some research 25 million around the world are using bitcoin. There is an estimated 39 million blind people in the world (doesn't say what levels they are) and lets say only 10% of them use the internet or have the resources to do so, that would leave us at 3.9 million users. There is no research on what amount of the users are using any cryptocurrencies but I was able to locate a post from 2014 at about an actual blind person attempting to use a wallet and saying his JAWS screen reader was in-compatible (sources: 1. https://www.reddit.com/r/Bitcoin/comments/1ufacn/bitcoin_wallets_are_inaccessible_for_blind_people/ 2. https://www.coindesk.com/bitcoin-needs-accessible-visually-impaired) Since then I have found nothing in the recent years. I guess you could also bring up the topic that if their screen readers are compatible with exchange websites they could buy and store the coins there, but we all know how that's going to end.

Bitcoin for blind people is quite possible if there would be new technology that will be created by our IT experts. Well technology evolves, there are already some technology for blind people, it serves as their thing to express their opinion, that is how technology can give to us. So I think this techbology will be also provided to blind people to use bitcoin, if that things happen, iy would be great because as we all know bitcoin is such a safe haven and it helps so many people. So if blind people would try it using technology that will be created by IT experts they will see how good bitcoin is.

You should read this thread https://bt.irlbtc.com/view/5222338 (dunno if you search before you create a new thread and didn't found this). Then wait for similar suggestions and discussion pop-up here. After that, lock this thread.

Seriously, I have tried to imagine this in some different ways to see whether it would be possible, but the way I see it, it would be difficult to achieve. But anyway, nothing is impossible, you just have to believe that it is possible to do whatever it is and then work hard towards it.

Cryptocurrency addresses are always a very long combination of numbers and letters. Even if it was possible to input a touch and read feature into these cryptocurrency wallet apps, I am wondering how these people will be doing all that, like copying the address of the receiver and then pasting and sending and stuff. Let's just wait until then.

What we interact with are wallets and it's wallet that are not friendly to blind people. But that might not be the case always as bitcoin gets more popularity. Bitcoin's official wallet is also an open source project and I don't think we could see a text to speech feature or a braille friendly feature anytime soon. A third party, that could even be us who thinks of that group of people should work on creating one.
