Honestly, this is an amazing project if ever someone will continue to develop or give attention to this idea. That's how technology works, solving a certain problem and giving ease to its users.
yeah that's what i am pointing if there will someone answered about this not being successful or other company will make other venture to help Blind people,but well yeah we don't know future as people may consider things or not to become possible.
and i agree on that because there are many people who's Blind and not only them but the Deaf people as well who may need help to make them invest this Currency of the future.this is not only for normal people but also for all the people in the world.
Deaf persons would never face issues investing or earning with cryptocurrencies like bitcoins but that in case of blind I am a bit doubtful. Bitcoins are a digital currency which are only available on the internet. Also accessing bitcoins is never a easy and 1-2 clicks task but instead it requires some knowledge and also login into our wallets is a bit complex.
In situation like OP mentioned, there are no ways for blind persons to get acquainted with bitcoins. Even if they do enter the field, they would never be sure about their security because even if they lose some specific amount of funds, they couldn't even spot those transactions which might never be an ease for them.
