As the title asks, is it safe to store your coins in Bitstamp's online wallet?
I would say no, i keep about max of $5 change in there but anything more than that would be stupid unless you can afford to loose it.
History has shown us that the last place you want to store your bitcoins is on an exchange.
Im not saying Bitstamp will run off wih any customers coins but they may get hacked again and this time not be able to pay back everyone.
Best store them offline till needed.
Nice suggestion by him. Moreover, did bitstamp refund the Bitcoins hacked recently?
Simple message to op:
If you don't care about liquidity but a lot about security, go for cold storage
If you care about liquidity, evaluate how much money you need regularly and maintain something like a hot wallet to satisfy needs.
