No problem. @steembasicincome is a share based service that will give you upvotes (small) for the life of your Steem account. One share won't give much, but it is over the life of the platform each day, so it adds up over time... even better when you win it and you don't need to pay for it!

If you do decide to buy a share, then it costs 1 STEEM, and you (as the sponsor) get one share, but you also get a bonus share to gift to someone else. In my case, I bought a share and I gifted the other share to you. You don't need to do anything... in a few days, you should start to see a vote from @steembasicincome (or one of the pool accounts @sbi1, @sbi2.... ).
