Just some friends, Didn't talk about bitcoin with everyone but just close friends to avoid the regular misunderstandings between others who I don't have a strong relationship with, now the ones I told are regularly talking with me about it, even 1 or 2 already using bitcoin sometimes.

There are few truly offline wallets if you have intention in long-term safe holding of bitcoin, Bitcoin Core and Armory (which still require bitcoin core blocks installed) are excellent options. Being truly offline and require almost no trust in a third party.
Electrum, although secure, still require some trust in the operators, the benefit is the no need to reinstall the blockchain as a whole, You can even get a hardware "Ledger Blue" if you would like to take security to the maximum.

IMO the rise in fees is unlikely with the current improvements that happened and incoming to the bitcoin world, most likely the fees will decrease with the provision of more space for transactions in blocks, but even if it doesn't fall, I don't see it rising much more than now, particularly if it's not needed within 1-2 blocks.
