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???
As of now my biggest cryptocurrency mistake is when I do panic selling because I am afraid that the volume of that token will become 0. Once realize what I have im totally become frustrated and I think I will do not do it again.
