Most likely a lot of your coins are erc20 base off ethereum so can easily store on myetherwallet using the nano ledger s (which I think is essential for almost everyone) and it has the modt amount of supported coins. Google nano ledger s supported coins to look at the list. You most likely won't be able to get every coin on the ledger but it's way safer. Beyond erc20, each coin will have an individual wallet but the seed never leaves the ledger which is much safer.
Only buy a ledger from official site if possible or check their list of authorized resellers. If someone gets a hold of your secret key they can recover your wallets on another ledger or compatible encryption wallet. This is why even if you lose the ledger you don't actually lose the funds since they are stored offline.
