This is so really hard to say special cause its difficult to explain specialty in short word
Some of them are given below:
Its a type of currency which know as peer to peer currency and this permit to send and receive money without help of broker or third party involvement
Every bitcoin holder can review their account information after sending money or receiving money from their account.
After all kind of transection bitcoin recorded sufficient proof of every client and account holder through different facilities.
Buying and selling process is so much easier than other currency
I think above mention quotation is sufficient for proving that how much special the bitcoin is.
Firstly, it is safe in contrast to other currencies, yet it does not require investments to make bitcoin good enough to try and not be lazy, and then everything will turn out. Bitcoin is one of the first and quite expensive coins. Personally, bitcoin is special for me, I have not yet found a coin equal to bitcoin.
