Learn the fundamentals of btc first, there are plenty of btc 101 guides on the internet, I've included one from our blog in a link below. Secondly, or maybe even before, read up on blockchain tech/distributed ledger, after all, it's the technology behind cryptocurrency. There's a link to a blockchain guide below as well. Once you feel a little more comfortable with these (the learning never stops), then move on to wallets--how to securely store your coins, how to perform transactions to and from your wallet. After this, look into exchange platforms. Start thinking about how you want to purchase bitcoins, credit card, in person, a bank transfer? There are exchange platforms that support these methods better than others. There's no right way to start your research, but it is imperative that you gain a basic understanding of all these aspects within crypto before you start trying to invest a large amount of funds. Remember, btc transactions are irreversible, so triple check everything before hitting 'send!' Also, never invest more than you can afford to lose.
