It's really interesting about the Friday dips. I wonder if it is tied to stock market traders cashing out before the weekend to avoid any crazy drops that might happen? With more money coming in from the financial markets all the time, who knows!
Anyway, I upvoted you, but unfortunately I'm new to #steemit so it probably didn't make much difference :) But I donated a small amount of BTC to go towards your laptop fund. Keep up the good work!
