Does the absence of 8 MB block imply inadequacy in decentralized crypto currency or does it make it even
more centralized?If the coders are reliable, does the 8 MB lag pose any threat that could raise any doubt of
non-performance?
Increasing the blocksize ALWAYS come with a centralizing factor, since the rule of "the bigger the blocksize, the harder to host your own node" always applies, therefore, you want to avoid raising the blocksize for as long as possible.
Reducing on-chain size with segwit and Schnorr sigs et al are ways to go around this, some consider anything but legacy transaction not safe, then again, if you don't consider that safe, you can't be a BCashier pretending BCash is a better idea.
