First of all, there are so many websites and projects that want to steal your money, even if it's not a rugpull, even if they make a legit website, eventually we all know that it will end and it will not exists any longer. I personally know that it's going to hurt a lot of people and it should not really be a big deal.
I personally think that if you are investing into something that you are not certain about the website, you are already making a mistake and you should avoid that.
If you say like this, it's mean Bitcoin isn't trusted and this forum also not trusted too because these projects will end
I don't think it's not a big deal when you have invested your money on there, it's not about the amount you have invested, but it's about the trustworthy the project is. I still think there are few legit projects which really focus about the real use case than the making money purpose.
