Multi crypto wallet for Android version 4

But what about unbanked people? I thought one of the main goals of BTC was to offer a solution to them?

That's why i proposed a paper wallet
I just don't see the point in running an old (potentially vulnerable) wallet on an old (vulnerable) OS. In order to use a paper wallet, the OP's friend just needs one friend with a clean pc + printer... Sure, a paper wallet is only suitable for holding, but still, he can hold in a very secure way.

I'm not sure bip38 is very suitable for beginners because they need to manage an additional information. The iancoleman page allows to create HD paper wallet with a seed, it can be a good solution for beginners since they just need to remember the mnemonic seed with that.

Most paper wallet generators, like the offline version of https://www.bitaddress.org/, have bip38 encryption build right into the tool... Just click the "paper wallet" tab and enter a strong password... That's all.

Iancoleman's page (at least the offline version) is nice to, like you say, it's basically a HD paper wallet, but missing the encryption... The bottom line is that we agree that a paper wallet is a good idear for somebody who can't affort a decent phone nor a decent home computer

Bitcoin itself has no influence over who develops on top of it or how it's interacted with.

Considering how many old phones there are out there in the world I'm surprised there isn't a wallet specifically maintained for broke people with old systems. There's got to be some demand for it.

I'm pretty sure there's a market, however, i just don't think it's a good idear to fill this market...

If you develop a wallet that's compiled for such an old version of android, they'll point a finger at your wallet every time they lose funds because of a vulnerability in the underlying OS.
Granted, there are also vulnerability's in newer versions, but at least they'll still receive patches.

I agree with you it's quite easy to create one, but it could be confusing for beginners, because it can be hard for them to understand why they got a private key, an address and a password, they could easily confound the address and the private key moreover, so you need to be very educational if you do that IMO.

Yes he can safely store his funds into paper wallets and use his old phone as an everyday wallet with only small amounts in it.
For example he can dispatch his funds into several paper wallets and then only import one wallet at once time to spend his funds.

I guess you'd have to spray it in disclaimers and urge people to upgrade if they can, or tell them they're on their own. That'll probably scare them away so you'd never get a download.

If I were in that position I'd appreciate at least one option. If your machinery is that lowly you're likely to be a bit poor, or a shocking luddite.

If he really can't get a new phone not so expensive with newer android then it should use web wallet like blockchain.
