How about when transferring funds via offline to another wallet.? Well upon checking in whois the site is old and i think owner is from UK and its looks legit..
I am just afraid since i never heard that there are wallet that you can use offline..
for something sensitive like your cold storage wallet, it is best to use the most popular code. and it is not just because of trust but also because the more popular some code is, the more it is reviewed and as a result it will have far less possible bugs.
i suggest using: https://www.bitaddress.org/ instead. it is more popular and more tested.
its repo: https://github.com/pointbiz/bitaddress.org
I just confuse what i will do next ..
I think i'm satisfied with multibit hd its more simple but let me try bitaddress i'm interested with this wallet how this works.
but as far as bitaddress goes it uses your browser (Javascript) to generate your private keys and as the random number generation goes, it uses your random mouse movement.
after the generation is over (100%) it shows you a new page which you can copy the bitcoin address (on the left saying SHARE in green) and private key (on the right saying SECRET in red) and you are done.
there are other tabs that are generated which you can use. and i think they are pretty self explanatory. for example the paper wallet tab gives you a pretty paper wallet to print.
you can also copy the generated private key in first tab and paste it in the last tab (wallet details) and encrypt it with BIP38 passphrase.
i am not familiar with bitaddress but maybe i will need it once i want to save a bitcoin for holding purposes and hold it for a long time because this kind of wallet is just like a cold storage..
