Investment is a personal decision; one cannot rely entirely on someone else. Improving one's own understanding is the most important.

There is a fool on YouTube named blockchaindaily, when ETH was about to rise to 4100, I was going to sell, and this fool said it was the last chance under 4000 for ETH, which resulted in me being stuck until now.

Damn that stinky fool, what opportunity, it was a trap that killed me.
