here. Basically, it is a way to reward Steemians and encourage long term involvement on Steemit.For this post, I got a 0.17 worth of upvote. By sending 5 STEEM to @steembasicincome with your name, you get 5 SBI shares. So you already have the gift, and there is no further action required from you. SBI will take some time (usually 2-3 days) to register your share and you can check how many shares you have
