Investing in Bitcoins, wise choice!
Just make sure you read about Bitcoin, as Bitcoin can be volatile.

Mining is such a big term, mining yourself will most likely not be worth it.
Mining Equipment is very expensive and investing in Mining Sites are mostly scammy!

I would use FIAT and buy some Bitcoin, store them in a Wallet or use Trading to increase that amount.
But before you start trading, read and educate yourself. Its not as easy as it sounds!
