As much as movement in the markets from charting follow a repetitive pattern, it is not still a good choice to compare the historic  movement of bitcoins to the historic movement of stocks. If anything should be referred back to, It should also be the history of bitcoins not the history of stock.

Just look at it, for reference purpose. There is no conclusion at the end of looking at your reference, the writers are not ding it to presure you into making a certain decision, the choice is still left to you, because the consequences from your decision good or bad are left to you too.
