Bitcoin, easier to trade and store, besides providing security.
Only if your computer isn't full of virus/trojans/worms. You can't actually say that your PC is secure. There might be a key logger on your computer and don't even know it. I believe the cyberworld is full of scammers and hackers, anytime you can become a victim by one of them. I think in terms of security, gold is better. Your PC is just so exposed to the Internet and there are tons of exceptional hackers out there just watching us.
The world is also full of thieves and robbers. And don't forget about government as well which may also want to set their greedy eyes on your gold that you have providently buried in the backyard of your home...
Maybe, your neighbor is spying on you this very moment
As you mentioned there are a lot of problems and inconvenience and insecurity while storing our money in gold, as gold has some volume while there is no any issue with bitcoin like that, bitcoin is a virtual currency and these are locked in your wallet and no one have access to your bitcoins but only your mind have access to them.
