You will end up praying that the crash from $70-$100k takes us back below $20k to buy back in.

We're at $11k with next-to-zero FOMO.
LOL, I think people already FOMOed with bitcoin, around $11,000. Nearly 7 months of bull run, that is too long and bitcoin has gone very far from its start. I could be wrong but I will keep my principle to stay away from FOMO, and keep my patience to be safe and have better chances. Months ago, no one believed that bitcoin would even drop to $6,000, but it actually dropped deeper than that range. From now on, I will keep waiting (taking profits of rest of my bitcoin, and waiting for chances to buy back).
