If you didn't know, if you purchased $10k worth of gems during a sale (100$ offer turns into 50$), you would get approx. 270k gems, how long would all these gems last? Would you even need that many gems (I guess unlimited YouTube content)?

Why would you even consider spending that much money on gems? It doesn't worth it.

Plus , I don't think 10k would break the game's economy. I mean there is already a huge gap between spenders and non-spenders, so that ship has already sailed.

If your youtube channel can generate the 10k loss then the answer is pretty obvious. Go for it. But I doubt if that's the case

Take everything with moderation.

I tell you what, you give me the $10k and I will find out.
