As a bitcoin investor, I do not encourage us to invest and store bitcoin through a third party because that goes against its original criteria. But I have to admit that not everyone knows how to use non-custodial wallets, DEXs... so for those who don't have basic knowledge of technology or are not too confident in their ability to hold it themselves. Buying bitcoin shares through ETFs is a good solution.
I see many people against investing through ETFs but we are not in their shoes and we are not like them. We should not impose our thoughts on them.
