I am never going to maintain my own wallet
If you really don't trust your skills in protecting your money, maybe you should try diversification? Have multiple online wallets, instead of only one.
But IMHO you should take a look at stuff like Armory and its offline wallets. It's not that complicated.
Its not only a matter of skill, I had a wallet a year and a half ago when I was first checking it out... Its a matter of what I want to spend my time on... even the online exchanges are a pain to deal with compared to just accepting a credit card. I have no desire to spend time keeping track of some file.
If bit-floor comes back online, I think the only answer is to just sell every bit-coin as soon as I get it. The issue with doing that is that it really ups the cost of accepting bit-coins, as there will be higher percentage of fees if im doing lots of little withdrawals.
Reading this makes me want to weep. Mtgox, Intersango, Bitcoinica, Bitfloor, I am aware of these before of course, but seeing this from a traders perspective is something new for me.
Nobody will use bitcoin if it always happens like this!!
Really we cannot keep recommending bitcoin to traders and recomending that they use exchanges that are not safe.
And with out exchanges that are safe and trusted, bitcoin cannot grow.
I think the fact that it has not been a priority is because security is hard. Think how much money banks spend on security... And even with all that, the money is FDIC insured, just incase. Lots of people in the bitcoin community like to bad mouth the banking industry, credit card companies, and the dollar... But could you imagine if those things were run like bitcoin?! The world would fall apart.
EDIT:
I want to add something somewhat positive... this time we are in as it relates to bitcoins is really like the wild west. The bandits come in and rob the train because the people who run the train dont know any better. Overtime things will improve. But again, because this is all just a game, not a necessity (what choice did people have in 1850), who knows if people will care enough to fix the system before it crashes one last time.
