But.... but... Will I have to wait 10 minutes for first confirmation when I buy my coffee with my Bitcoin Cash?!?!?!
Much worse than this , as the 10 minutes is merely the average. You could be waiting hours for the first confirmation , even if the blocks are near empty.
Everything that does Segwit can be done as also hard fork, as the malleability fix.
Even if they do manage to fix all the problems with flex trans and HF in this change , I don't see this happening anytime soon and if it does happen in 6 months I guarantee there is going to be some severe bugs
By than bitcoin BTC will be using LN for months with more competent devs supporting it
