theoretically: if you can mine blocks then you can certainly include your own transactions in the block.
practically: you are competing with every other miner on the planet to find the next block. If it happen you get the block reward plus you get to choose which transactions are included in your block. and if somebody else wins you get no say in the matter Unless you have a very large mining operation, the chance of you winning is so small that it's never going to happen.
miiners who do make new blocks today may choose to include their own transactions in their blocks.

Bitcoin Halal? you can start asking yourself: how you gain Bitcoin, from where you collect it and what you do with it?
the answer is simple.

Always keep your personal keys and password like private key in a safe place protected from stole and loose, its your keys keep them with you safe

basically if you lost your private key, you will never retrieve it again unless you will try to contact their support for taking chances.
certainly there is no way to go backwards from the public key to the private key, that would mean that anyone could steal your Bitcoin

Gambling games with bitcoins offer the same method as fiat currencies , really i did not try it, but the best way for me is learn and studying the bitcoin to gain from services and invest much better
