ETFs made Bitcoin attractive to investors and it also made Bitcoin easier and safer to acquire for average people. I use a mobile bank and in my bank, I have an option to buy and hold ETFs. I can transfer my whole balance within seconds on my ETF account that's managed by my local bank and I can trade with ETFS instantly. After accepting Bitcoin ETFs, now I can do it in my bank. This way, I save lots of time, fees and most importantly I know that I'm secured because its managed by local and heavily regulated bank. I'm not afraid of hacks or anything similar because I'm protected. This is a huge benefit for the average person, it makes everything smooth and easy but it's only good for trading, I still prefer to hold my coins on my Bitcoin wallet.
