Yes. Once you have bitcoin in your wallet, it is yours to spend or transfer as you see fit, and no one can take it away from you. There are some fringe cases where hackers or malware attacks can potentially gain access to your wallet, but I don't want to go into too much detail here. The most important thing is that you keep your private keys or backup seed phrases for your wallet secured from unwanted access.
I am not sure I understand what you are trying to say here.
Yes. Once you have bitcoin in your wallet, you can use it to buy products and services from any company that accepts the cryptocurrency, or you can send it to a bitcoin exchange like Coinbase or Binance and then withdraw fiat currency into your bank account. Most bitcoin exchanges are only available in certain countries, so check to see if yours is supported before opening an account with them.
Bitcoin is a decentralized system, so your wallet does not rely on any central banks or government institutions. That means your bitcoins are yours, and only yours, to spend as you like!
But thanks once again for the time and replies.
No problem, happy to help. If you have any more questions, do not hesitate to ask.
