New Guy Wants to HODL and Needs Wallet Advice

Hi,

I am a steemit novice, and this is my first time posting. I apologize to anybody who doesn't have the patience for my rookie nonsense. I'm sure this topic has been addressed many times before, but I have only found piecemeal information while searching through older steemit posts and google.

Every day I read about a new wallet or cryptocurrency storage innovation, and I am having a hard time synthesizing all the information i've found, so I wanted to see if there might be anybody in the steemit community who can offer me sound advice.

I am trying to find a FREE cryptocurrency wallet. I can't really afford a hardware wallet right now. Ideally I want to find a single wallet/client that can store BTC, ETH, LTC, and several popular altcoins (like XLM, XRP, ETC, etc..). I am also interested in being able to access the wallet from an iOS mobile device.

Would like it to be somewhat user-friendly since I consider myself a layman, but I'm not a total putz so I am comfortable with some level of difficulty/challenge.

What's the best free wallet available that would suit my needs? Perhaps someone can provide me with a link to trustworthy reviews or a table with a breakdown of the pros/cons of various wallets?

I would like to be able to store my cryptocurrency for maybe 2-3 years without having to worry about where my cryptocurrency is and be able to access it easily even if i go months without using it.

Thanks! All advice and information about cryptocurrency wallets is welcome!

Some i've considered are Jaxx, Electrum, and possibly Exodus (although i don't know much about exodus. perhaps osmeone can offer some helpful info on that one in particular?)

Thanks for all your help! And I am looking forward to getting more involved in the community as i learn new things, and try to HODL my coins on this crazy exciting roller coaster ride to the moon!
