Dear SIR @tasnim-tamanna ,First of all, thank you very much for posting so beautiful, we generally have very little idea about Bitcoin, many of us do not know Bitcoin without working with Bitcoin,

SIR was very good for your posting, because you provided the right information through which many will benefit, thank you so much for posting so beautiful and will help others by providing such information in future.

After knowing some things then bitcoin should start working,

For example: ...... Bitcoin is the sign currency traded through the Open Source Cryptographic Protocol. There are no financial institutions, regulatory bodies, or fixed houses for Bitcoin transactions. All processes of Bitcoin are completed online through an open source software or through a web site. In 2008, Satoshi Nakamoto introduced this currency system.

So if you share some things with me please do not (-upvote) please
