Thanks all! I am now in control of my BCH.

Let me share my experience.

After much debate, I finally decided to use Electron Cash 2.9.3.
1. Moved my BTC to new PC into new Electrum wallet.
2. Downloaded 2.9.3 electron cash.
3. When I first opened the electron cash wallet, since I had electrum configured previously, the wallet came with wallet_default (with 2fa) and logged me into my wallet. It quickly synchronized with BCH balance. I was quite happy with easy process. Yet, I tried to send my BCH to exchange, and I came with an error (error: The transaction was rejected by network rules. (16: mandatory-script-verify-flag-failed (Signature must use SIGHASH_FORKID))).

So I became quite concerned and my search around web continued. Ultimately I came across someone with same issue and long be hold, I was on way to a solution.

4. Move the wallet_default file from the electron cash folder to other folder on your computer.
5. Create brand new wallet, name it something different.
6. Then create new wallet using existing seed and disable 2fa (steps previously provided by escrow.ms ... Thanks!!)

This worked for me. I am sure many may have already described this before, but wanted to share this experience if noob like me is trying to work with electron cash wallet.

I still would like to know what people thing about storing BCH in electron cash wallet vs big exchange (which I feel like are less secure compared to wallet on computer)...any thoughts?
