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???
Ouch. My friend tried to convince me in NXT and Ignis, but I saw the huge pumped price of 24$ or something like that and a large supply of 1 billion. That was a signal to back down.
I have sold few Ethereum coins and price gone up x3. That was all for me, I guess I had luck and some brains so far.
