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!
But bitcoin wasnt a good investment for newbie since this coin has a huge price that newly investor may hard to buy,but why not try ethereum,more cheaper but good potential and almost perfect platform.
Bitcoin nowadays are being harder to speculate not like ethereum that has been used by 80% of going ico now,or those just finished project
