Hi, it seems that you are new to all this. All of us were at one time or other. I suggest don't jump in to anything too much before you learn a bit about crypto. Like others said, electrum is really good. I don't suggest that you hold your coins long term on an exchange, they tend to get hacked once in a while. It's safer to hold them in a cold wallet (if you do it right). For larger amounts, many people like to use a trezor or ledger wallet, but that's probably overkill for most of us. There is no hurry, its not going anywhere. Take your time and learn a bit before jumping in. it's not a get rich quick scheme (although I think bitcoin will go up long term). Don't get caught by a scam. And NEVER give away your passphrase to anyone. The bitcoin isn't really stored on your computer. You might think it is but anyone with your pass phrase can take the bitcoin from any where in the world (probably even the space station if they have internet lol). Good luck!
