Of course, all yours. And thank you. I never expected to actually earn my first bitcoins this way. Oh well, you're in my personal history notebook now :)
Well, thank YOU! I'm extremely pleased with the chart, you gave me good service for the money and i hope that this exhange leaved you as pleased as i am. Very cool that these were your first coins earned!
Excel is kinda not my best thing, and step charts is not that great there. Quick try and I got this. Hope it can help. Couldn't fit everything at the bottom, so it's either a year or block height.
Can you just put the block height and then the years in brackets under them using some editor and then write under it "block height and approximated time, (years)" and change the upper text to just "block subsidy, (coins per block)" & move the upper text more to left so it's clear that it refers to the vertical line. If you can do these, it would be perfect!
