You can buy Bitcoin from this forum but you'll have to be careful when buying Bitcoin because sometimes new members do not know how to buy Bitcoin from trusted members and they get scammed by scammers. If you want to buy Bitcoin from this forum then you must have to find a reputable and trusted members with a Legendary rank at least, and only then you should confirm the deal. I would also recommend you to have an escrow so you will be safe from any possible scammers.
You can also purchase Bitcoin from decentralized as well as centralized exchanges. But, if your country has blocked centralized exchanges then you should consider buying from decentralized exchanges. While it's possible to buy Bitcoin from decentralized exchange but still you should be careful when buying from decentralized exchanges. Still, if you find a good and reputable one then you can purchase from them without any issue. When it comes to centralized exchanges then my experience with Binance has been good so far, but still I won't vouch for anyone. Do your own research and then purchase Bitcoin.
I would also advice you to learn about Bitcoin wallets and when you purchased your Bitcoin then withdraw those to your own personal wallet instead of allowing them on those custodial wallets. You should learn about wallet software like Electrum in detail and once you are sure that you have learnt enough about it then create your wallet with that software and save your Private key and Pass phrase in a secure location. I would also encourage you to make your wallet a cold wallet because if it is connected to internet then you may face problems from hackers.
