I would try coinbase.com. It is easier for newer members and isn't confusing. (I would post a referral link, but apparently that's spam.
) There are also other exchanges where you can buy bitcoin. It is best, after purchasing these bitcoin, to place inside cold storage. I personally like my bitcoins in paper wallets for the most part. Keep your private keys in a safe place and don't share them with anybody.
To generate private keys, I would use bitcoinaddress.com. Basically it is a website that generates private keys for you. I checked the website on scamadvisor and it says the site is trusted and that was enough for me at least.
To find ways to earn more bitcoin that you can store away safely go to earnthosebitcoin.com
There are also countless of Youtube videos to watch, but be careful. Some people on YouTube don't know what they are talking about. Always be careful and do your research.
Bitcoin.org will tell you a lot of things that you don't know about Bitcoin and how it works. GL
Ranked to most safe to least safe way to store your Bitcoin is as follows:
Paper Wallet > Hardware Wallet > Online Wallet > Exchange
Of course there are caveats to each, but use your discretion and pick the one that suits closest to your needs.
