Re: IOTA - the scheme is being pumped hard now don't fall for the trap
IOTA has PoW, yet it can be easily attacked, so much, that you need to have a centralized Coordinator. Why is that, PoW in Iota does not secure it? You cant just add massive amounts of PoW to secure it? But instead rely on 1 special Coordinator? What a baby.
Coordinator protects against 34% attacks, it's not related to anti-spam.
I think you are confusing the way IOTA works with the way Byteball works.
I learned a lot about Byteball during my last testing, I think it's you who confuse that.
If you can attack it, go ahead attack it, your last "attack" which stalled the network for 6h, was due to a bug in the archiving of units, not anything with the consensus algorithm of Byteball or PoW, and because the 12 witnesses are still run my main dev and not other known real world entities.
Then it's a no-brainer for you to bet, for example, 8 BTC. Easy money for you. So?
I bet you there is other flaws and bugs in Byteball, as there is in any software, and in IOTA - but IOTA has a bug which cant be fixed - a conceptual retarded mistake. 
I can repeat my attack again and again until all bugs are fixed and then I'll do the attack once again. What do you think of that?
