If you increase the number of miners, you won't pump BTC price. You won't increase the BTC distribution.
The only thing which is gonna change is the difficulty.
More miners = More hashrate on BTC network = difficulty increasing
If you cannot exchange BTC with FIAT legaly in your country, you should have a look on Bisq for example, or Localbitcoin (but here KYC is needed if I remember well)
Ok if i connect to multiple miners and offer a miner method how i can get profitable and the other miners and how is the limit of possibility of losing
If you want to calculate how profitable you will be with mining, you have to know some things :
-your kw/h price (is electricity cheap where you live ?) In general, you will need a kw/h price < 0.05usd to be profitable, but this data changes.
-how much you have to spend on ASICs : when will you hit ROI ? If you buy used ASICs ROI is easier to hit, but your ASICs could be unstable or not working if you don't buy from a good seller.
-how much taxes you will have to pay on your profit
-how much taxes you will need to pay for customs if you buy miners from USA or China for example
You can add some other costs as : a place to host your miners, they are ultra-noisy and creates a strong hot temperature in the room they are.
+ is it legal in your country to mine cryptocurrencies ? I mean, it will be difficult to hide this kind of electrical consumption from the governement / electricity provider.
