base on my studying in bitcoin through reading in the different opinion of others here,
the advantage of bitcoin was the anonymity, easy to use, no problem with money transfer,
and you can do have savings like a bank without any personal documents that needed.
safe and secured.
This is infact the biggest advantage of bitcoin as you are able to send and receive coins world wide and you are your own bank when it comes to bitcoin ,in short the freedom and control you have with your asset is the biggest advantage of bitcoin.
