I bought steem early on. Only started seriously posting and commenting like 6 months ago.

I do not think I will ever get to 1000 upvotes averaged at $0.1 each since my topic is not very popular. But other bloggers in more popular topics will eventually reach this goal. You have to remember that Steem currently only has 1 million members. As membership and activity grow there will be larger groups of people with up voting potential. Also the higher the price of Steem the less SP needed for each $0.1 upvote.
