Strike launches Stacks to sort Bitcoin savings into goal-based buckets

Strike wants your Bitcoin to have a filing system.

On October 7, 2026, the Bitcoin-focused financial app founded by Jack Mallers launched Stacks. The feature lets users divide their Bitcoin holdings into up to five named buckets inside a single account.

It works like the old envelope method for household budgeting. Rent money goes in one envelope, vacation money in another, and nobody accidentally spends the mortgage on concert tickets. Strike's version does the same thing, except every envelope holds Bitcoin.

Users can create as many as five stacks, each with its own name. The idea is goal-based saving, so one stack might be earmarked for a house down payment while another sits as a long-term reserve.

Moving Bitcoin between stacks costs nothing. Transfers between stacks and the main balance carry no fees and no limits.

There is one rule worth knowing. If you want to send Bitcoin outside of Strike, it has to travel back to the main balance first.

Each stack can also run its own recurring purchase plan, with no fee attached. This is dollar-cost averaging, usually shortened to DCA.

For the uninitiated, DCA means buying a fixed dollar amount on a regular schedule, regardless of price. Instead of trying to time the market, you buy a little every week or month and let the averages work themselves out.
