Well, what I did is that I only use 1 wallet. However, I am going to generate multiple private keys thru bitaddress.org. I still have to download the webpage of the bitaddress.org and run it locally on my desktop unit. Disconnected the internet and enabled all firewall for all application without exception both incoming and outgoing for I am using windows OS.
From hereon, those generated private keys from the bitaddress.org, will be then be imported to Electrum. Thus, as a result I only need one wallet but had multiple bitcoin addresses.
I do not use the auto generated phase seed of electrum for I strongly believe in the near future a powerful computer will have enough computing power to crack and generate those seed phases and expose all the 16 different addresses or more along with it.
Having a private keys is edge since this is supported on most light client and full client nodes.
16 different privkey? sounds nitemarish
In lightweight client: Electrum, after generating the phase seed, automatically by default a 16 unique BTC addresses are generated for. All of which were generated from the public key as its seed. The public key is generated from the private keys as its seed in generation. While private is generated from the phase seed. A secret phase seed.
