Self custody vs. Broker

Hi all,

I posted recently asking what would be the best ways and advice on how a beginner would go about self custody. After many good comments, it seems like my strategy, if I were to do self custody would be:

1. Buy BTC from Strike (no fees)
2. Wait until I have gathered around $2-3k worth of BTC and transfer to HW wallet. (Minding UTXOs)
3. Keep stacking in wallet for 30 years (do I need to switch HW wallets as time goes by?)

That seems to be the approach if I were to decide to invest long-term in BTC and have self custody of my coins.

However, I've been reading tons of horror stories of people getting hacked and drained for their life savings in BTC. That is just so shocking and scary to me. From telling people to not even open their wallets daily, or using a completely different computer to access the wallet. Either way, my plan to hold is for 2 reasons. One for retirement, the other as a safety net if something were to happen to me (on top of life insurance). This means my wife needs to understand how to access the funds, or survivors.

Regardless, it just got me thinking a lot and I wanted to ask here.

What is the difference between self custody and taking on all the risk as opposed to holding within say Robinhood. I would not plan on connecting my RH account to anything since nothing in crypto interests me other than buying and holding BTC long-term.

As I understand it RH insurers accounts up to $500,000. I understand other crypto exchanges have become insolvent like Celsius and FTX, but RH is more than just crypto. I find it really hard to believe they'd become insolvent. And if they did, wouldn't I be insured on an account less than $500,000?

I understand my market buys and spreads might be a little higher with RH, and understand reddit in general doesn't like RH too much. But the example would work with WeBull or any other broker that offers crypto now.

So what are the pros and cons of self custody vs. Brokerage crypto? Is it smarter for a layman non techy investor to just head the safe route that is insured?
