10k to harvest NEM?

I recently start investing in NEM and I read some articles about it. Most of the YouTube video’s shows that I need 10k to harvest in NEM.
Currently I don’t have the money to buy 10k NEM’s. Should I wait until it will drop to a point that I could buy more?

I also found this article
Does this methods still works?

Unfortunately the video is already offline.

I would like to hear from you guys soon!

Ps: if my English is not correct feel free to correct me.

Yes. You need 10k vested balance to start harvesting.
