Just recently I've decided to invest in Bitcoin and have chosen to buy shares in Fidelity's FBTC Exchange-Traded-Fund.
My choice was primarily between Fidelity's FBTC and Blackrock's IBIT. I chose FBTC because I like and trust Fidelity's service and I like their Trading Dashboard features.
Is Buying Shares of a BTC ETF a good way for non-tech new (late-to the game) investors to invest in BTC?
Yes, ETFs are the recommended method for both low tech people and those that are overall not familiar with the practices necessary to secure your Bitcoin. Keep in mind that mistakes with Bitcoin are not reversible, so I highly recommend educating yourself deeply before you try to do self custody with any significant amount. For the time being you are better off joining us through the ETF. Welcome!
