I only understand one thing from the bitcoin and thats, it is best way to to transact as compared to the banking system. When transact through my bank the transactions are completely visible to people around me, it can be tracked by the government and it is also taxed heavily. While in my country bitcoin being illegal tender is not under radar by government due to insufficient regulations for the same. So I get the advantages of transiting through bitcoin. I can be anonymous and I can send funds to my friends and family with full confidence and that too with no extra taxes. This way I can earn online and I can spend online with the help of bitcoin.

That is how I know bitcoin but I am not keen in terms of its technological aspects. So I just expressed the fact which I love about it.
