It seems this project has the potential to generate attractive revenue for all investors and this idea is also nice with the working product it is a good choice to pick this right time.
It seems to me that the interest of investors is visible when the project quickly collects money.
Maybe you are right. But I still think that with low cost, you need a strong advertising company.
Advertising of course you need. But a good project a lot of advertising is not necessary! Investors already see the prospect.
Bounty is also a paid option. But the payment is delayed and invisible, since these tokens can also be sold to investors. I think the best option is a combination of bounty and advertising.
You're right, this combination is usually better, but it also depends on the specifics of the project and Airchain need to consider this also.
