10 minute delta

The 10 minute delta really should be a percentage rather than a value. $1 change in zencash for example is a world of difference compared to $1 change in bitcoin. Percentage change would be much more meaningful.

I also reiterate that the "conversion rate" be put as a 2nd row in the coin column. It really feels more logical to be there and would clean up an entire column. But I guess if I'm the only one suggesting this, it's just me :)
