The biggest risk for me based on my experience is being complacent and greedy, I should have become an advocate of the word HODL back five years ago, it is so easy to accumulate 1 full Bitcoin 5 years ago on bounty campaigns when Bitcoin is still cheap, and there are good and profitable projects to promote, not having an insight in finance is the biggest risk.

Insight is what carries you to hold on to your portfolio and accumulate more, lack of it and being easily tempted to sell for a small profit when a bigger profit is yet to come is a disaster.
