Welcome to the community,
My personal recommendation would be to not do anything with them when you are pressed by time.
No matter how much you have, you are dealing with (some kind of) money and should be respectful of your belongings and know what you are doing.
Instead of risking your funds, I would advice to play around in the Testnet (testnet.bitshares.eu), create an account, trade in the (rather small) TEST-Exchange and get familiar with the concept of BitShares.
If you run into problems, drop us a line and we can figure it out. You may also want to join the bitshares slack: slack.bitshares.org
Once you feel good using BitShares, you can go ahead and do stuff with your real money, e.g. trade, short, or anythign else.
Cheers
