Hey there! Since you are new, I suggest trading with Bitcoin, as it is the first cryptocurrency and widely accepted by many. It seems to be growing a lot lately, so it is still a good investment to date.
Once you familiarized yourself with the crypto world, you can check out other altcoins, airdrops, ICOs, and many more!
As for investing Bitcoin, get a good Bitcoin Wallet, like CoinBase, or for more security, Electrum, Mycelium etc.
You can get Bitcoins from exchanges, so try to search them up to know better. Good luck!
I'm also new to crypto currency. I'm currently on my study mode right now. Your recommendation is good since BTC is already established and currently still on the rise. However, ETH or Etherium is gaining grounds and in terms of investing you can buy more ETH than BTC right now. Depending on your capacity and intent both investments are good. Although I am a bit inclined with ETH. More power to you.
