I am setting up a RasPi2 and leaning more towards MultiBit just because it looks easy to install... I have zero experience in this area and would love some input....
Thank you
Bitcoin Core is better for you
also we can help network with running node it
It is nice for people to run nodes. But if this is going to be a main wallet I would suggest using a cold wallet. Most likely a lightweight wallet so you don't have to download the chain when you plug it online. Use it only for the wallet, don't surf internet or other things on it.
Also make a backup via paper wallet or usb. You will want to store it in a secure location. But you don't want to use just one copy where if it get's corrupt your losing your coins.
