A friend who just started using crypto asked me if it's ok to have his Bitcoin and USDT on Binance or other exchanges for a long time. He was worried about safety, government issues, and whether it's better to move his crypto to a personal wallet.
Honestly, I didn't have a clear answer for him, so I thought to ask here.

Do you leave your crypto on exchanges or you do you move it immediately?

What risks should people in Nigeria consider when deciding?

Is there any safety to use for exchanges or wallets?

I believe, your advice will not just help him but others here too who may have the same question.
