digital asset custody services
With Bitcoin, going with non-custodial or self-custodial to stick with Satoshi Nakamoto's vision.
This will continue to lead to a mass adoption very quickly.
It's part of Bitcoin adoption but it is not what Satoshi Nakamoto created Bitcoin for. Business companies saw Bitcoin potential as well as threats for their business and they knew that they only can join the Bitcoin party, but they want to control it somewhat, so custodial services created.
Can this even be referred to as bitcoin adoption? I don't think so because when you buy bitcoin yourself and own your keys, you are adopting bitcoin. But when you pay some company or a corrupt bankster that tells you they buy bitcoin in your stead, then you are not adopting bitcoin. You are instead adopting that centralized and corrupt system that may not even have as much bitcoin as they tell you they have!
People have options: self-custodial or custodial, and they can make decision. Careful and knowledgeable people will surely choose self-custodial as they are aware of risk of custodians from banks, business to Bitcoin-related services. Self-custodial wallets are free to access, use, and full control so it's effortless to use non-custodial wallets and have as well as control your own Bitcoin banks.
