Plain, simple, useful post here man.
I am into trading (and bot-automated trading) since some months now.
Bigger frustration to me is seeing that the crypto world (exchanges, charting platforms, services) is still too much "under development" or "beta version" or "we interrupted the service" and so on.
We need to wait, maybe, to have a more reliable, efficient, stable, long lasting base to trade in this environment, don't you think so?
I think your right, probably the best example i have when Ether was going around 20$ a piece and crashed due to the DOA hack. Lost a lot of money only because i could not trade on Kraken during the hack. Ouch. But heey, never a dull moment in Cryptoland!
Yep, I did wrong when DAO went on Poloniex and immediately started going down without ever coming back to the initial price. And, of course, many DDOS which prevented from operate on exchanges when it would have been profitable. And also exchanges like Cryptsy :-\
