Hardware wallets which I personally use trezor t, I've never had an issue and their interface is simplistic, one of the hands down best ways I've seen yet, but I like to diversify a bit. Anyone have issues with these? I doubt it.

Paperwallets I've used the github zip of bitaddress.org I've personally never had an issue storing btc on it(inalways make 3 copies) but I was wondering if anyone else had...what I mean is your bitcoin being swept or the private key doesnt work, like its wrong?

Vanitygen64 github zip, I've used this to make a "1SenDBTcPo. 0000000000000 .JqzLotgAck " address I gave it about .01 BTC to see if it was malicious code, thus far it's been sitting there. I store it on an encrypted usb, which has never seen the net, and is password protected. I was wondering if anyone had any issues with their btc being swept with this or their private key doesnt work, I have tested another one and it worked fine but with like .0008 BTC.

I've never used a mobile wallet and never intend to. Unless its 100% off line.
