I've heard a lot of responses from SegWit supporters but no real hard evidence at why Bitcoin needs to be changed. I've been using Bitcoin every day for nearly 4 years now. My original Bitcoin QT client hasn't been upgraded for years. I have sent and received thousands of transactions with many different addresses, online wallets, QT, etc.
Bitcoin has worked so well, I don't understand the issue?!
SO WHAT if it takes 10-30 minutes for a confirmation? It takes days/weeks to get paid by the bank.
I have been sending the recommended fee of 0.0001 for years until recently when blocks started slowing down. Now I send 0.00015 (OMG 15 cents!) and my payments are confirmed under 30 minutes every time, usually 15 minutes.
I've said it before, LEAVE BITCOIN ALONE.
If it's obsolete, then let a better Alt coin take over. That's free market.
It's NOT WORTH THE RISK of changing Bitcoin, and potentially RUINING a perfectly good crypto-currency. All because you are too lazy to wait 30 minutes for a confirmation.
