I would like to start a private sale of my tokens but for safety purpose without a website.
That may be safe for you but will be too risky for the investors or people who buy your tokens.
we as investors can answer this directly mate,if we will invest in "One Man Project?" of course not because there is no assurance of this being safe and specially since he is the only one whos involved then he can just run easily .
I never saw developers or a team member stated they won't make an official site because of security reasons. So, it is strange for me you are saying "for safety purpose, no site". Commonly, I won't be interested in a project which has no site. For me, it is only a scam way if someone plans to sell tokens without an official site or trying to hide an important part of a project.
Those reasons he made is simply just to save Him from criticism and also to those who really don't understand what investing is all about here.
