Altcoin storage: where to HODL?

[Seppo22]

Where do people store their altcoins which are not ERC20 compliant and not supported by any of the hardware wallets?

I've got a Trezor, but it's limited in coins supported. I have a variety of coins on various exchanges, but would like to store them offline for safe keeping. Am I stuck with installing native software wallets for each coin? What about paper wallets?

Thanks for any advice you can provide.

Most of these token usally have desktop wallet and I believe you can save your tokens on them, desktop wallet is not that bad but if you can get hard ware wallet it is the best for security, this is very important

Some coins (Dogecoin) have paper wallet.
Some coins (Monero, Waves) have deterministic seed.
And for some other coins you don't have other choice than keeping somewhere safe the wallet.dat (or equivalent) file.

But each and every coin has its own community. Go and ask for each coin you are interested in, since there's no universal solution.

Such coins as you described are not so many, and what prevents just to store them on a computer? It might just be an offline pc.

That is a problem if they do not have their own wallet.
You should beware of that. Most of them should have one or a website where you can store it with seeds as your log in.
Better to have that kind of service or else you are risking money that could lead to just being stolen.
