user56857: Is bitcoin only mined as a block reward? 
Can't someone mine from the bitcoin treasury even if he/she doesn't adds block?
If bitcoin can only be mined as block reward; on what standards starting bit coins were mined and who mined them? 
Non-technical answer please!

user51948: Yes, bitcoin is only mined as a block reward, there is no other way to mine, there is no such thing as a 'bitcoin treasury' (as you found out in your previous question). So adding blocks is the only way to get a block reward and earn bitcoins.
The very first bitcoins were mined by satoshi nakamoto, in basically the same way blocks are still mined today.
