And this the history and bitcoin table when discovered in the world from 2009.[Using USD Rate 2017]

From this list we know bitcoin is not stable , frequently make increase and reduction on price.
Is there a possibility of a decline in the price of the bitcoin future , in doing so we must make a choice better invest a bitcoin or not ?
The only thing that I see is an obvious and steady progress when I look at the yearly pricess.
2013 retraced compared to 2014 ATH wise because of the MtGox debacle . The next year of 2015 had a lot of other FUDdish news, and generally it took these 2 following years after the 2013 crash for the market to recover confidence of Bitcoin.
Of course, the moment I started learned about Bitcoin, I started buying every month, so I bought while the rest of people were bitching and moaning during 2013-2015, now im obviously up and I can take a lot of damage until I would see myself losing money, so in the case BTC enters a long term bear market you know what to do.
