lol thats kind of big amount so being worried is part of the story I guess 😂😂😂But hope you had already received the bitcoin by now and also maybe you can lock this thread since your questions had been answered .so the spamming will Be prevented on this side
If you want to buy btc with cash it is better to find first a local wallet that could provide you an option to buy bitcoin directly to the application. It is fast and reliable for you to find this type of wallet or trading application for you to avoid scam.
