Mining or investing in cryptocurrency?

Hi guys. How are you?
I hope you will be interested in my post. I need some your good advice.
Recently, about a month ago, I started mining. Before that, I was only trading on the stock exchange, but as a passive source of income I decided to set up a mining farm.
As u know the most expensive part of the mining fam is video cards. So I bought a mining farm for $3600
In the beginning of the May I bought video cards by $400. Now it costs$850.
I early June the farm brought $30 per day, now the volume fell to$22-24 per day.
The video cards hype is simply huge, even the weakest for mining with a capacity of 15 MH/s sells by $450 now.
What`s wrong with AMD and NVIDIA? Common guys!
The huge demand for cards and resulted in such a sharp increase in their value.
I counted income per day, with $30 the farm pays for itself in 6 month , now this process can be delayed up to 8 month because income fell to$21-24 per day.
How do you think if there is a certain amount of money, like 100 thousand dollars
Will it be clever to buy farms and part of investing on the stock exchange, or to throw the entire amount into crypt and wait for growth on exchange.
Best regards!
