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?
To my mind, Bitcoin Spot ETFs are a good way for beginners to buy Bitcoins but if they want to HODL bitcoins, then I suggest them to learn more about Bitcoin over time and focus on hardware wallet and how to create a cold wallet and store their bitcoins safely.
In my country, local banks offer ETF investments to their customers. With mobile or internet bank, you can easily move money from your main account to investment account and buy ETFs within seconds. You can also sell them within seconds and immediately transfer money from investment account to main account, all of these are part of the bank's ecosystem and you do not transfer money outside of the bank, which is very handy to my mind, especially for beginners.
