Thanks, rest assured now
Another (silly question): the wallet address alphabet is always small capital right? Cause in MEW I saw some are big capital some are small capital:
e.g.: 0x...Ad...
while once printed out it becomes:
e.g.: 0x...ad...

Don't worry, addresses aren't case sensitive
This is not a silly question at all, and deserves a little bit of understanding.
What you wrote above, "0x......ad......" is the so-called *real* (or raw) ethereum address, which is represented in pure hexadecimal format.
In this format, the addresses with some capital letters are check-summed, while the addresses with all small letters are not check-summed, but otherwise, both addresses are exactly the same address, and both can be used without worry (i.e. technically speaking, NOT case sensitive, as WooTz already mentioned).
The check sum feature is used by some compatible wallet software to check that the address is valid and ensure that the address was not mistyped.
However, in the case of bitcoin, when we send bitcoins to another address, we do not use this address (hexadecimal form), but instead use a Base-58 format (for example 1P2cWsE3GVdB6BLKafkqxHtWAZgFt5Jvm3) which does not contain characters that will confuse users, i.e. 0, O, I and l), and has checksum and version number built-in.
In this instance, the address
*is case-sensitive* and must be entered EXACTLY as it is.
