Token Pre Sale: Have you benefitted before?

[Fidelia]

For some tokens, they don't give airdrop tasks for people to claim tokens for free, they do a pre sale of the token at very cheap prices prior for it's listing. Have you ever participated in a token Pre Sale? Which token was that and did you benefit from the pre sale after the token was listed on your exchanges?

I have never bought any tokens during the presale, I am not very comfortable buying during the presale.
