I've heard a variety of theories on when to lease regarding price of Steem or SBD; however, none of these really fit my strategy on how I would use the SP once I leased it. When I did decide to lease it, I did so in order to build my audience for my blog, give myself better upvotes, and curate more articles to increase my engagement in the community. The results have been very promising after 1 month so I renewed my leases. The price of Steem didn't really factor in because I would have to purchase Steem for Powering Up anyways or buy SBD and build my SP through purchases of upvotes. Either way, I believe the lease was best for me. It just isn't the best for everyone.
