rudeness is a sign of the opponent's rightness. Answer the question: how will you solve the problem of expensive commissions when the price of bitcoin rises?
will you pay $ 1000 for the transfer or mounth stand in line for $ 100?
L2 solutions are meant to take care of transaction costs, if/when they become unbearable. Which, in a world devoid of mempool spam by Bitmain and their minions, won't happen before massive adoption.
How did bcash plan to solve the problem? With a larger highway? It's a non solution, bloating the blockchain linearly with the number*size (not the monetary amount) of transactions. This would have made it impossible to keep bitcoin alive on user-maintained full nodes.
And what about eth? It's never been a solution to that problem. It's a proprietary token, with the master doing as he pleases and considering switching to PoS just to be sure. Sod immutability and distributed ledgers.
But I guess many WO'ers have told you these things already. You're just being blind, or deaf, or both.
(Rudeness might also be a sign of weariness after reading so many mindless repetitions.)
