You got a deal 30 steempower for 60 days for 3 sbd.
I'll have the amount in 24 hours.

Sounds good

once i get the sbd i'll make a contract and you accept the deal. So the blockchain records of our deal. just a security procaution

No problem. I got a little carried away on voting today, so I was going to add an extra day so make it 61 if you could just make sure you get 100% for 60 days.

hmm...wait can you lower it a bit.

I get 1sbd=40 steempower for 30 days. It probably a little more but let's go with 40.
2sbd=40 steempower for 60 days
but they ran out of steempower. So 2.1-2.3 sbd would be a good price for 60 days due to scarcity. 3sbd seems a little to much. i'll pay about 2.2

How about 2.2 for 60 days and you remember where you leased it from (just) a few times when you upvote over the next few months?

I do not understand what you mean by the last part: "remember where you leased it from (just) a few times when you upvote over the next few months"
