OT but I'm in a situation where I have hundreds of different altcoins on a handful of exchanges. I'm looking to move these into my own wallets but it seems that I will need to get so many different wallets that it's not worth the hassle. Why isn't there a wallet which can handle all kind of cryptocurrencies? The most I've seen in one is like 10.

As someone working on cryptocurrency wallets its a much more difficult task than you think. First you'd have to be compatible with multiple chains, then you have to support multiple contracts on those multiple chains.

Then theres tokens that start out as ERC-20 and eventually want to move to their own chains, which means your wallet is gonna have to be responsible for the swap.

On iOS specifically theres distribution issues where some cryptotokens are allowed and some aren't.

Also one way that wallets make money is by listing fees, so if you don't pay up forget about your coin getting listed. I heard from Vertcoin community that Exodus specifically was asking for 200,000 USD for a listing

I think that's what Jaxx is trying to do. They don't have hundreds of different coins but they have almost 50. https://decentral.zendesk.com/hc/en-us/articles/218373867-Wh...

Jaxx works wonky and doesn't support ERC20 tokens though.

Coinomi supports a surprising number of coins, and I have used it as an intermediary. I'm not sure that I would use it for long-term storage without knowing more about the company.

The Ledger Nano S supports "apps" that can provide compatibility with many coins, and could theoretically support many more. (https://www.ledgerwallet.com/cryptocurrencies)
