December 2017 during the high of highs, I made a huge mistake, I allowed greed and fomo, ignored my gut and bought into NXT because I was chasing Ignis airdrop. The coin has since tanked and I still have not received the airdrop. Nxt is probably 80/90 down.
What is your biggest cryptocurrency mistake???
My biggest crypto mistake is not studying thoroughly crypto last year. I have known crypto by early quarter last year but I did not take seriously because of an important event in my life. Probably if I have grabbed the opportunity earlier, I may have a good profit since last year.
