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 mistake was assuming that $400 is the bottom price for Ethereum

Gosh, I had been ready to put all I have on bet it wouldn't have fallen under 400usd back in july)))) thanks god i hadn't eventually)
