I always suggest if you have a reasonable amount of money, anything over a few hundred dollars, to store via a hardware wallet.  Ledger, Trezor or Keepkey make great products, however I believe Ledger Nano S's are the best and most affordable option.  They also offer a great list of altcoin support and add new ones constantly and great Bitcoin hardfork support.  This week they are also offering 21% discount!  Check it out.
