if i ask you, if you would buy bitcoin right now, where would you go? its just a question
If you don't mind KYC, you can register for Binance, KuCoin, or other CEX exchanges. But if you don't want to do KYC, you can choose DEX, like hodlhold.com, or other options.
You should have a goal before buying Bitcoin, whether for trading or investing because both are different. If you want to trade, you have to be able to determine when you can buy Bitcoin at a low price, sell it at a high price, and repeat this process to get big profits.
If you want to invest, you don't need to do that. Just focus on buying Bitcoin once a week or once a month and do that continuously.
But you should learn about analysis first to determine when to buy and sell. The important thing is that you can be calm when the price goes down and see it as an opportunity to buy Bitcoin again.
It seems like he still doesn't have any basic knowledge about bitcoin and the market . So I think he should take the time to learn what bitcoin is, what cryptocurrency is, basic concepts like decentralization , non custodial wallets , centralized exchanges...he shouldn't rush to buy bitcoin or into trading without basic knowledge. If he buys bitcoin now or rushes into trading, it will only make him lose money faster without bringing him any benefit.
OP, there is a lot of beginner material right on the forum that you can find on your own or can easily be found on YouTube channels . You should learn the basics instead of diving into investing or trading .
