cold storage preferred for investment
Although technically not cold storage, a Trezor hardware wallet is probably the easiest way to get started. It's a good trade-off between convenience and security.
also some way I can spend it without using banks while I travel abroad. Please help this noob.
The main "problem" will be finding merchants who accept Bitcoin. You could sell Bitcoin P2P, but there's risks involved in the physical trade, especially when you're in an unfamiliar country.
Depending on how much you plan to bring with you, a mobile wallet (for instance Electrum or Mycelium) is easy to use. But it's a hot wallet, so only add what you can afford to lose.
It's worth learning and testing a bit before going "big": learn how to store Bitcoin, think about a secure backup location for your seed words, and read up on the potential risk factors. To start:
