There was nothing inherently wrong with Mt. Gox as a place to buy BTC. It was trading it and storing it on Gox that got you burned. I lost 0.6 BTC because I was planning on margin trading some but that was only a fraction of my holdings at the time.
Cherry picking much? Returns for anything looks awesome if you are comparing it to its bottom. BTC is up 15% this year which is good but nothing to shout about.
- Past performance has plateaued for years.
- Use cases are niche instead of regular transactions.
- Since the use cases are niche there is few uptake drivers.
