i don't know why coinmarketcap has become popular for people as a go to when they want to check the price! it is the worst place you can check the price from. it gives you the average, the charts aren't accurate,...
but the actual lowest price of bitcoin recoded ~
there you go:
https://bitcoincharts.com/charts/mtgoxUSD#czsg2010-06-01zeg2010-08-17ztgSzm1g10zm2g25$0.05 on July 2010.
since you love (the meaningless) market cap so much by July 2010 supply of bitcoin was
19 months * ~30 days * 144 blocks/day * 50
BTC/block = 4,104,000
market cap of bitcoin = 4,104,000 * 0.05 = ~$205,200
Thats a nice analysis and literally I did not know anything about bitcoin since those very first day. Actually never thought about it because that wasn't necessary one.
But when I come across such information then it tells us in rarity how fast and far we have come since those days. Can imagine easily how wonderful it owl have been back in the time when the reward was around 50 btc per block. I mean easily one can perform the action with computer process power and have those much BTC.
Well, yeah coin market is kind of too basic version that we see today and that is why most of the people like it. May be not all of them are being to techie.
