I've never joined a presale for altcoins because many people say that this presale will end up being a scam. I've never received free funds from cryptocurrency, so I'm not interested in joining Presale.
If I get free funds from a cryptocurrency contest, maybe I will use it for my real world needs, I don't want to join a Presale that ultimately doesn't provide convincing value.
I'm sure members who have a lot of experience in cryptocurrency often also join Presale, but for me I'm not interested in joining Presale, even though I have the funds, I don't think I'm interested in joining either.
