That is most likely a query for an extended dialogue, much less for an q&a discussion board 🙂 There are too many opinions on learn how to, primarily based on the specified outcomes and values (and paranoia). The upper the values, the extra necessary is a correct stress examined storage system. My present answer could be a mixture of digital machines and completely different {hardware}.
I consider storing a number of altcoins in a number of chilly wallets (offline). My main concern could be knowledge loss as a consequence of damaged {hardware}. Therefor I would have two or higher three backups. I might create a number of offline PCs in digital machines/environments, and still have an offline Linux, and perhaps an older MacOSX and/or some RaspberryPIs (all offline). All programs have one benefit over the opposite. Within the digital machines I might attempt to setup a pockets, by compiling myself. If not, I take a default pockets. As soon as the process is “clear”, I can do the identical on an offline PC. It is astounding, what number of dependencies there are…
I might set up the default wallets on the offline machines, word down the priv keys and/or seeds, seize a photograph of the priv key/seeds (be sure that your cell would not sync the picture to the community, and delete it after downloading!), and maintain it written down and/or someplace in a veracrypt container on the completely different offline PCs. It’s good to distribute, hardly all break on the similar time. Additionally I word down the general public keys and/or addresses. Then within the exchanges, one may ship keys to “my” addresses.
I would not obtain all of the blockchain(s), that’s not required. For instance in Bitcoin, it’s enough to have the priv key, to get it loaded in an SPV pockets like Electrum. In Ethereum there’s MyEtherWallet. Different cryptos solely have the “full shopper”, which make it a bit tougher, with regards to spending. The shoppers won’t acknowledge the funds, which have been despatched from an trade to the chilly storage since its inception. So long as there isn’t a SPV sort pockets, you would need to obtain the chain as much as the purpose, the place you acquired final funds, or assemble a tx your self, and ship it to the community. I’ve accomplished this a number of occasions with bitcoin, however by no means for altcoins…
You requested for an environment friendly course of, my guess is, there is not. I go away it to the viewers, to persuade me of the other 🙂 There are too many dependencies and completely different necessities, even when you have the technical understanding, implementing a pockets and having the ability to chilly storage nonetheless requires a superb pondering on course of and attempting it out regularely. I would be very irritated, if I feel I’ve saved my knowledge, simply to find in the future, issues have modified and I can’t entry funds!
Right here within the discussion board are many hyperlinks to the key phrase “chilly storage”, and over at bitcointalk as nicely. So my publish is in no way overlaying all and each choices. Possibly folks can share some extra choices.
