My mistake was when I did some panic selling some medical token only to wake up to find out that the price has quadruple, I really regretted selling my token out cheaply.
My biggest crypto mistake is that when I join in the translation campaign, I rely and trust the campaign and I see it good and I thought will give me a good profit, but it end up only to be a scam, I have not earned even a single amount in the translation I did.. Lesson learned, do not easily trust a good campaign.
