Thanks for sharing your thoughts.
It is interesting to see other points of view for crypto trading.
For the Cryptsy problem of a possible crash, i would suggest to cashout partial profits in BTC and/or USD.
Offcourse the altcoins for trading need to stay there, but taking out a part as "savings" (15-30% per month?) is a good idea
to avoid maximum loss and reduce the floating risk. It would be sad if you loose all again, think of the time you spend.
As i had written it before that one dude i know made it from 6k up to 200k and got Goxed in the end

.
(i managed to initialise a BTC withdraw ~72h before mt.Gox crashed, my altcoins where not in danger)
