0.5 btc means you are taking about roughly $200. Its almost impossible to do it just online, you can try affiliate marketing if know your way around it you can earn hundreds of dollars per month but other than this i dont think its possible. You can obviously try those captcha jobs and other jobs offered in services section of forum, but you will not even earn 0.05 per month i think.

There is no need for any identify for creating a wallet, you don't even need a name. Yeah some wallets like coinbase ask for it because they are trading website also. But if you create wallet on blockchain.info then you need almost nothing, just a email that too is optional. But I personally like the desktop wallet, they don't even need a email heh.

The confusion is obviously because of the same name. Now of a person has only known about epay.info if he sees epay soem where he will obviously think it's epay.info as he is unaware that there is a epay.com
As for me I am aware of both of them
