So I've been investing in cryptocurrencies for a few months now and I've been trying to figure out the best storage solutions for different coins. I just ordered a Ledger Nano S so I plan on using that when it arrives. One wallet that I found really interesting for ETH is myetherwallet. It seems to be a paper wallet generator, so the keys aren't stored online or anything, but it has an online interface that you can use to interact with the paper wallet. I think that this functionality is very cool, is there a similar paper wallet and interface hybrid for Bitcoin? I'm currently using electrum which works fine, but I was just curious if there was something similar to myetherwallet, because it seems like a pretty secure, decent way to have a wallet set up. It allows for cold storage, but gives an easy way to access funds later without need to download software.
There's an altcoin who's running an ICO right now who's offering a wallet services and that eidoo and you can download it on play store. But I suggest to read the thread of the dev of that wallet so that you can see how there wallet works. And for reading there whitepaper their service is quitely good and I think they will get a huge success on there ICO.
