'postponed over two times and when it was launched'
It's working now? You probably weren't around but people like you were saying the same thing for ethereum when it launched months late and had really buggy code on release.
'tested on a testnet '
Are you dumb? Dawn 1.0, 2.0, 3.0 were all testnets running eos.io software. Not to mention to code got audited by multiple companies before June 1st.
'EXTREMELY CENTRALIZED'
Dumbest shit I've ever heard. You have a brain - use it. 21 nodes is much more decentralized than every other coin in the top 10.
Everything you've said is either insignificant and won't effect eos in any way or is just plain wrong.
