I think your greatest problem could be the name. So many coins have been created, tht it's difficult to think of a new name, and to get a .com domain to go with it. For example, I've just bought ERC20coin.com, and that seems to have had toxic associations in the recent past. There is even a Youtube video about "ERC20 coin" being a scam coin. Any expired or dropped name is likely to have been misused in the past, and you don't want to start off with bad associations.
Mostly ICO projects are using .io domains, .com aren't used very often. But yeah, there are so many projects already created, so it can be difficult to get decent name without dark history.
Yea this. Even though .com domain usually looks more legit for the laypeople, crypto projects have been using other domains for some time now. .net, .io, .org, .network, .co, .cash, and many other. So yea, their options are getting wider. Technically the domain TLDs doesn't mean crap anyway, using the good TLDs just simply looks more legit.
