I hope I can visit Bangladesh someday @hazifzullah, thanks. The best way to learn about @steembasicincome is to join their Discord channel - also read the FAQ here.
To participate you have to either be nominated by someone else or pay 1 Steem and nominate someone else. This buys each of you one share, and you each get one partial upvote per post - look out for votes from sbi and then a number.
Someone nominated me for Steem Basic Income so I thought it would be good to pay it forward and encourage the type of content I like to see!
