I think IOTA will be the settlement network of the 21 century. bitcoin is just too expensive, too old tech etc you know it all.

I love Nxt but I would say Eth is prob 2nd Gen at this point.

Still around IOTA and belive it is a greate step forward , i have been reading the whitepaper and posts here. I still can not get my head around milestone node.  So the tangle on milestone server counts more then what other nodes have?  and also in this case the use of the server will always be there and it would be so that IOTA is not 100% trustless. 

right, so when the network is big enough they take the server offline. thank you for making it clear

This interview with Dom is worthwhile to read. You can know some IOTA team philosophy from it -

It is indeed quantum resistant, Iota uses Winternitz signing which is quantum-immune. For more info check part 4.3 of http://188.138.57.93/tangle.pdf.

With IOTA's technology generating seed from an address wouldn't be too easy even if it is a super computer.

It is possible and sure to transfer iotas to the same address, you can receive iotas (several transactions) on the same address, no problem. Only if you spend iotas from this address it's no so sure further.

No, better =

BTC = -2
NXT = -1
ETH = 0
Iota = 1
Previous coin were just drafts for Iota :-)

One of IOTA's advantages which has not been appropriately appreciated is her simplicity. IOTA is a very simple protocol. One of reasons that it is much simpler than other protocols like Bitcoin and Ethereum is that IOTA gets rid of miners. In IOTA, the transaction issuers are also transaction approvers and they are no longer decoupled as in Bitcoin and Ethereum which use miners as the transactions approvers.

We all know how many frictions the miners have brought into the Bitcoin system. The third party (such as miners in PoW, stakers in PoS, witnesses and delegates in other systems) naturally makes the system more complicated (in other words, more vulnerable) and brings more frictions into it.

Many people have mentioned that a significant reason that TCP/IP and WWW protocols had been chosen and adopted by the market is that they both are very simple protocols. We can probably say that a simpler protocol is easier to be adopted by the market.
