Don't tell me to use a centralized exchange, been not active in crypto space means that a centralized exchange can collapse before you come back, I want something in my control.
If you have a better option, don't hesitate to share.
Well, putting an early order on centralized exchange is your best choice when you're busy 24 hours a day. Busy people will always be busy, but if you really want to buy, you can spend a few minutes of your time to keep yourself updated on the price of Bitcoin. I'm a busy person as well (I'm having sleeps of lesser than 6 hours already which makes me groggy all the time) but still, I'm allotting at least a few minutes of my time to keep myself updated. Can't you do that?
Using a centralized exchange and putting an early order is the best option for you. The market will not adjust base on what you're doing lol. The market doesn't care about you, or what you're doing. You're the one to adjust if you want to buy when the market is dipping. You aren't active in the crypto space, but you want to buy? If you want to buy, have some time. If you want profits, allocate some time. If you want to buy Bitcoin, use a Centralized exchange if you're "BUSY", and use a DEX if you prefer to be anonymous.
Already shared my opinion, and what you want will not work for you. All of us who want to make profit in crypto allocated some of our time to keep us updated with the happenings on the market including corrections.
