Bitcoin was created to solve a couple of big cryptocurrency flaws. First, it was designed to prevent crypto coins from being fraudulently duplicated. Think about how easy it is to make copies of your computer’s data—documents, photos, files, etc.

What Do You Need to Invest in Bitcoin?
You don't need much to invest in Bitcoin, all you need is the following:
Personal identification documents
Bank account information
Wrong! You don’t necessarily need all these to buy bitcoins. You can buy bitcoins from a decentralized exchange that does not require kyc or you can buy from p2p service.
Keep in mind—if you’re going to be purchasing coins through a stockbroker, you may not need to supply your personal information or financial information because your stockbroker will likely have all that on record.
Stockbroker? I assume you mean exchange. An exchange will only have your personal information when you have completed KYC on the exchange.
3. Connect your wallet to a bank account
When you’ve obtained your wallet, you’ll need to link it to your bank account. This enables you to purchase coins and sell coins. Alternatively, your bank account may be linked to your cryptocurrency exchange account.
Wallets and exchanges are different things. Do not mistake the two. Bitcoin wallets do not need to be connected to your bank account, neither are you required to perform KYC on your bitcoin wallet.
