Focusing on the Bitfinex hack is going to make your dissertation boring IMO.
I plan on discussing the August 2016 Bitfinex hack and the impact this had on people's confidence in bitcoin, and so my aims and objectives are to discuss bitcoin's merits as a currency, and whether it truly has the potential to rival fiat currencies in the long-term despite the numerous hacking setbacks etc.
Anyone with a brain, who is not an active trader, should have not lost a single penny in such an *hack*. The coins that one has on an exchange, are not yours. They are an IOU, and it seems like plenty of people are very ignorant about this.
I was also planning on running a questionnaire on here in the future to gauge people's feelings on how they felt before and after the Bitfinex hack in terms of confidence, how you feel the hack has impacted on the community and how you see bitcoin evolving in the next five years etc.
Zero impact because I was left unaffected. Bitfinex was shady long before that *hack*.
I would be happy to answer any questions and I'm very open to any suggestions or feedback on my planned dissertation!
Silk Road, Mt. Gox are much more interesting than Bitfinex.
