thank you @NeuroticFish, I will do that and buy a nano S.
Buying hardware wallets will not give you 100% security, especially if you do not learn how Bitcoin works. Even if you use HW, you should know that you are still at risk of something called clipboard malware and that you should always check the coin address on the hardware wallet screen and compare it with the coin address to which you send your transaction. The other thing is that backup (12 or 24 words) is much more important than HW itself, because anyone who comes into possession of those words can steal everything you own.
I am really a beginner, and i thought I have done something wrong with the adress and the compatibility with coinbase regarding the adress segwit native and others because I don't understand that.
