Thoughts on ETF's

So there's a few reasons I don't actually own BTC itself, but invest in the ETF which follows it's price.

1) Here in Canada we have a tax free savings account, meaning any profit I make from stock market investments is not taxed. So if I for instance put in 70k and it becomes a million 10 years later, I take that million fully tax free. Unlike if I own BTC and sell it, I have to pay capital gains tax which is massive in this country, especially if it's a lot of profit.

2) I have no intention of really using BTC to purchase things or use as a currency, it's purely for long term investment

3) I don't want to pay exorbitant fees when selling in the future, unlike the ETF which has minimal fees

Is there anything inherently wrong with my strategy other than "not your coin" sentiment, which is a fair point, although I don't think the stock will fold because it's a massive financial institution insured by the government.
