Thank you so much, great info! I just ordered the Nano S and selected the express shipping and they said it's come in a couple of days. So I'll probably keep the crypto in Kraken until that. One less place to pay fees and one less things to study and to make a mistake in 
I'll try to read super carefully how to transfer the cryptos from Kraken to the Nano S (and create folders etc. first). If there's an easy mistake you guys are aware I would naturally like to hear it so I can be even more careful. I'll transfer a small amount first to make sure it comes as expected. One page also suggested trying the backup option before you put any money to see one can make it work correctly. I don't know if this is a good idea or if something could go wrong because of it.
Really great that you understand the importance of hardware wallets because exchanges although are very trusted and heavy amounts are being stored and transacted, are always the risky option to store Bitcoins. I always suggest that rather spend $100 less in trading but always buy a hardware wallet and store your coins there to actually be the owner of your coins. No private keys in control means you don't own them. I'll try to read super carefully how to transfer the cryptos from Kraken to the Nano S (and create folders etc. first).

Anyways, good luck with the investment and trading you might do in future
.Thank you very much Lucius! Excellent info, I can't say it enough how grateful I am to you and everyone else so thanks again!!
Glad you actually read and liked the suggestions by fellow community members. So what have you decided how are you going to invest into crypto now? I wish you success with whatever you have decided though. Focus more in BTC rather altcoins, is my only suggestion.
