I have printed several ETH paper wallets via https://www.myetherwallet.com/
yesterday and have noticed that sometimes it gives me ETH Address with upper and lower characters and sometimes - only with lower characters, e.g.:
0xA0100A27374bAedd24504B9c02b8356Fa1dE54c8 << in browser I see this
0xa0100a27374baedd24504b9c02b8356fa1de54c8 << this one I see on "Print" pages
Well... as I understand "A" and "a" has different code in binary form...An I wrong?
Bitcoin addresses also does not recognize my address if I change "A" to "a".
ETH seems like it treats the same "A" and "a" in address line, but I can't understand the logic - WHY.
I am afraid to send funds to wrong address.
Thank you for comments or links etc.
