Has anyone heard of an attempt from current hardware wallet providers like Trezor or Keepkey to provide a secure and stable platform for IOTA to be stored in cold storage, whether it be a separate device or an update to Trezor, Keepkey, or even LedgerNano? If so, what is the news and/or can you cite some reputable sources? Thanks in advance. 

Hey guys. I'm new to the crypto world and I was just wandering is it better to buy bitcoin on coinbase or is there a better starting point? Also, I have ordered a Trezor hardware wallet but it hasn't arrived yet so how do I safely store my coin offline until my Trezor gets here? Thanks for any advice.
