Strike offers automatic DCA monthly/bi-weekly/weekly/daily/hourly (with no fees after the first week). Hourly really smoothes out your average buying price. They also let you set up target buys in advance to smash-buy dips without needing to constantly follow the price and this reduces FOMO about buying the dip if you’re busy at work or asleep when it happens. Then, when your stash reaches 0.01 BTC or whatever size of transaction you like to avoid small UTXOs, they auto-withdraw to your cold storage via a free on-chain transaction. Tax time might be painful with so many small hourly purchases, but I use coinledger.io to automate this so it should be fine. I don’t convert my salary to BTC automatically, but Strike also offers this via a virtual bank account that has an ACH routing number and account number that deposits directly into your Strike account, plus you can specify the percentage of each deposit that gets converted to BTC immediately. Very happy with Strike so far.
