Hello @mamun6 , I warmly welcome you to the world of steemit. Steemit is a blockchain where you earn by posting quality and contents.
I also want to use this medium to invite to join sporty-chain, a community where you can build your writing skills, share your sport views, get sport update and also grow in both your reputation and steem power.

I wish you success in all your activities on steemit. Once more,you are welcome.
