What was the first price you bought bitcoins at? Do you feel annoyed that you haven't purchased more?
This is more rhetorical question. I think everyone wants to buy bitcoin when coins price at the lowest price. And of course, the more you bought, the more profit you get.
I hear about BTC in 2013, but sigh my wallet in 2016, and buy BTC in march 2017 for $ 1000/coin...
