Financial support isn't enough. You must also have a good team that updates your peers every now and then, else your project will not get enough attention from the masses and might get foiled easily. The competition for the altcoin markets is always cut-throat, and even if you have loads of budget for your project, if it's not used correctly into something that really matters then it's a dire effort plus wasted money.
Usually a project that gains much exposure and positive reception are those who are good in marketing plus innovative features of the project. You don't necessarily need to have bounty campaigns that pay top dollar, just enough things to get your word out and an approachable team for that matter.
These things are already given when you are planning to start a project, without these things and you dare entering the market without proper executions is like you are executing yourself. In my opinion, in order for a project to stand out amongst so many projects clashing in the market, you need to be more exquisite than you could ever be, you have to surpass the limits of other projects, and those given factors you have mentioned will play a huge role for that, especially big funds.
Money move people (in a good way or bad way), that is why it is important as a leader of a project, you have to have a big amount of cash to hire smart people who could support you on making your project successful.
