So what offline wallet do you recommend?
never be a good idea to store your bitcoin in third party like an online wallet and exchange , it's okay if you stored low amount only just to spend daily purpose. but if you talking a large amount storing your bitcoin on an exchange in the long term really a blunder it's has proven on how mtgox , cryptsy and bitfinex claimed hacked it should be a good example.I have just came back to btc after 2 years, but i'm not going to keep all my BTC there, so I just have a little amount there to shop online and buy some steam games.
If i were you , you should not waste your money on buying those besides you are just back up to bitcoin world you should utilize and diversify the bitcoin that you remain in previous years not on wasting them but still its your decision though to make such action because its your own money.
Keeping money on exchange sites do have really risk of lossing it.
