With Bitcoin's price being almost $40,000... It's just making me wonder... now that I'm starting to pour more money into BTC... yeah i just can't help but wonder how secure Bitcoin is.

I understand that the checks and balances with everyone having to go through the ledger and "no cheating" can happen because everyone must agree before a transaction can go through...

But what about if they attack Bitcoin's software instead?

Every miner uses the newest Update... the updates are centralized:

1. It's officially hosted on one site, downloaded at a central location.
2. Not all miners check or look at the code or even work on it -- a few devs do. If those few devs decide to inject malicious code... everyone else is just going to download and implement it.
3. There are no real security checks with the updates -- no formal body of regulators or official code security team is going to check it for malware... yes, it's open source and everyone can view it -- but then you'd need volunteers to check it regularly. Often, people who check the code only do so after everyone updated already.

So I ask, as bitcoin gets more and more expensive and large financial institutions are considering pouring their holdings in ... the people behind the security code are legitimately not as decentralized.
