Please ask your price (hypothetically) : Advertising.estate OPT.estate TAKE.estate ReAll.estate Thank you.
None of them. I am not a fan of these new TLDs. The only one that seems half-decent is .sucks, which I think is coming out next year. If I had to choose a .estate then it wouldn't be one of those above, but instead "real.estate".
It's worth what someone is willing to pay. These are new domains and there will be a lot of fuss, some stupid money spent, but all because they are new and someone thinks it is a good idea. Only time will tell if they are or not. There is nothing to base their value off, but if you really want to push it then they are all terrible and not even worth the registration fee. There are not many words that will work well with it and - IMO - real.estate is the only one that fits comfortably. There is no ambiguity.
You quote is not correct. Premium domains registrar himself took (option). Domain world has changed. It happened...
I am not sure what you mean. I guess you are not a native speaker and meant something else other than quote. Look at all the other TLDs that came out before, but .com still rules. As it is what most people are used to. Rolling out new TLDs now is not enough, but instead time is required to get people used to them. What is most important is end users - they have not changed (yet). For most people, it's .com, with a few .org/.net but also their local ccTLD. This is what they remember most. Purely for search traffic, it can be domain.monkeypoop, it won't make too much of a difference. However, for type-ins, word-of-mouth, branding, etc, .com and (if it's applicable) the local ccTLD are the simplest and what wins. New TLDs that will "win" will likely be brands and/or TLDs that make sense in English/feel comfortable when saying them. But each to their own.
ICANN changed their rules, World didn't change. Change needs time and gTLD have none. There is no value to gTLDs right now. These are still "virgin" registries. Don't mix .com advantages with gTLDs. Yes they contain premium keywords but they are based on non premium TLDs.
