If I want to generate for example 10 Ethereum addresses and I want to use Myetherwallet , I have to create 10 different keystore/.json files and then use these files to access each address separately? Because that seems insanely annoying, considering that in principle it's advice against re-using the same address, I would have a bunch of these files to store, each with their own password...
Can I just get a file that can work as a seed that can spawn a bunch of different addresses? for example, you can use electrum, and save a file that you can load in electrum and have access to as many addresses as you want, not only 1 address per file. Is there any wallet that does this?
You need to know mew wallet is the most secured ethereum wallet for erc20 tokens because of its unique features,json file will assure your wallet address cant be compromised or copied by anyone,it is a unique ID for your wallets,you need the file abd your password to open your wallet,you can generate as much mew you want but you cant create a single key for all your wallets.
