Yes, they are very bad. Moreover GDAX has not a very good uptime. It is totally unfair that they are valued so much when there are way better exchanges.

No need to exagerate the situation. Bitcoin will be surely worth a lot more in the future, but I do not think this is the rise for all, and that we will never get, even though if it seems very possible.

It seems unlikely to me to talk about Bitfinex going the Mt Gox way. Talking about this possibility is for me the best way to create panic and to lead to this scenario. For this reason I will not be speculating on something I do not believe will happen.
