I've experienced network high fee and network congestion for 1 day can't get 1 confirmation.

So I'm searching for bitcoin segwit wallet.

What I found is no good wallet for it.

One is Electrum.
it's address is start with bc1 yeah it's great and it gave you private keys
BUT. blockchain.info can't search it's transaction.

seems like bc1 address is not compatible with old wallet and system.


another one is green address
yeah it's address start with 3 and compatible with other wallets and service
but it won't give you private key.
and even they give you private key it's no use.
Greenaddress is a Multisign wallet which need 2 private keys to move the funds.
I lost my rights on my coins.


So a few questions

1. is an address start with 3 is a multi sign address? that means you don't have full rights on you coins?
2. is an segwit address need to be a multi sign address?
3. which segwit wallet will give me the full right? (don't need others to approve)
4. if No.3 is no is that means segwit is a system that need someone to approve you transaction?
