At least you already have a good sense of confidence about investing in Bitcoin, even if you decide to buy shares instead of the actual Bitcoin itself, which you can actually store in your own wallet. However, if we're talking about whether it's a good method or not, buying ETF shares is certainly a good option. Moreover, the company you're referring to has a proven reputation, which I believe is beyond doubt. So, if that's what you feel is safest and most trustworthy, then that's the right choice for you.

Everyone has their own approach. However, if you want to invest in Bitcoin and want full control over your Bitcoin, then buying it on an exchange and sending it to your own Bitcoin wallet is the best option.

For now, you're on the right track. And I suggest you also start learning more about Bitcoin so you'll be more familiar with the investment instrument you're entering. I'm sure that once you learn more about Bitcoin, you'll become more confident in your long-term investment.
