Either back of the fag packet calculations gives a good idea of a 2 month migration cost being added to the chain, assuming everybody voluntarily moves over. So we do not get that promised transaction rate increase for a very long time in practice.
yep
but thats 2 months at best assumming ALL tx's were segwit migrators. remember usual tx flow of people paying people and spam fill blocks too. so imagine it like many months of mempool crashing and fee war price increases with still no guarantee's
other proposals of just blocksize increases (real blocksize increases) either dynamic or spoonfed fixed amount, dont rely on moving funds to cause it. so those options dont cause months of mempool bloating.
