So I bought some BTC at Kraken and Coinbase. I understand that it is not safe to keep them there, so I created an Exodus wallet...

-From Exodus, I printed the words, back-up link and password and I will rent a safety deposit box to store these.
-I saved these details for two days on my desktop since I was out of ink. Is this dangerous? I use Windows Defender...
-Are there any things I forget about the wallet?

The procedure looks simple to me. Just send my BTC to the wallet address and done. I guess it is alright to send all BTC at once, or is it better to do in parts? I know already that transfer in one time is much cheaper.

I'm sorry for the questions, but just want to be safe. Any other tips or recommendations are also welcome!

Thanks and good luck with all coins!
