Bitcoin ETF- time to invest?

Hello,
Now that many Bitcoin ETFs are approved including those from Fidelity and BlackRock and Schwab’s is coming soon, what is your take on investing on bitcoin through these instruments?

It might be time to SELL. The tiny amount of Bitcoin I have has doubled.

You probably got my money because I bought small amounts of two cryptocurrencies and lost half my ‘investment’. I have done better in the casinos.
