You may find some valuable tips to implement in your learning process and evolving trading/investment strategies in my 3-part series:
Did my best to sum up the core principles I learnt my first year.
Iota is an ERC-20 token, so any Ethereum wallet that supports ERC20s will do the job. Most people recommend a hardware wallet like Treznor or Ledger. MyEtherWallet is a good web-based soft wallet. Exodus and Jaxx are also good desktop ones, though not sure if either support Iota yet.
