I know about the wallet, but I don't think it's safe. I used to use Samourai bitcoin wallet, but instead my bitcoins disappeared, little by little it decreased (not from the price) I don't know why. that is what I feel. -snip-

Have you checked the transaction history in the Samourai wallet? From there, you can check if there are transactions that you do not recognize. (https://docs.samourai.io/wallet/usage#balance-and-transactions).
Another option, try importing seeds from the Samourai wallet to another wallet such as Electrum.

-snip- I switched to using a bitcoin wallet from an exchange that came from my country, until now it is still safe.

The wallet provided by the exchange is not entirely yours because you do not own the wallet's private key. Use it as needed for trading purposes does not as a main wallet in the long term.
