@kingscrown cold storage is the best option but for others be aware that if you buy a ledger nano s or trezor from a third party seller this can spell disaster later down the road. Always check for fingerprints on your ledger nano s and if there is any trace of tampering on package send back immediately. Only buy from ledger authorized reseller or directly from company. Paper wallets are also good but are complicated for newbies to use.
