Of course there are some fees for sending your Bitcoins from one wallet to other, and whether you send your Bitcoins from one online wallet to other or from online wallets to your offline wallet, you'll have to pay the transaction fees.

 if I understood Gemini they take a fee of 0,25% to convert fiat money to coins and from coins to other coins. Is the fee for moving money between my offline wallet and Gemini also 0,25%? If that's the case I think that could be worth it to have safety and full control. I am only investing around 1000$ so I will only get an offline wallet if the wallet itself is free. I haven't done so much research about the offline wallets yet but I really like the idea of decentralizing money

PS trying to quote you got a bit fucked up there sorry for that xD
