Bought 21000 SP for 5 bitcoin a couple of days ago, which is the bad news :(
The good news is that I'm using the steem power to offer a delegation service, on a month to month basis.
I've leased out 2 of my 3, 10K SP lots already, at 2% per month.
It's an interesting development of the ecosystem.
I came to the same conclusion about the price, but read some hit pieces on btc gold, so underestimated fork fomo.
