Shrimpy is how a generation of crypto holders learned that a portfolio could hold target weights automatically. This page is written by Trade Leopard, which does a related job — so it marks its own position on the map and states everyone else's mechanics as their documentation states them.
Set target weights across a basket — 50% BTC, 30% ETH, 20% SOL — connect your exchange accounts by API key, and Shrimpy would periodically rebalance: sell what had drifted above its target weight, buy what had drifted below. Spot only, thirty-plus exchanges, premium tiers around $13–19 a month. No entries, no exits, no stop losses — just allocation drift corrected on a schedule. It made the index-fund way of holding crypto normal.
Bitcoin IRA announced its acquisition of Shrimpy in November 2023, to build the rebalancing and DCA technology into its own retirement-account platform. The retail product wound down after that, and as of August 2026 shrimpy.io no longer serves a page — the app's domain does not resolve at all. A tool that trades your account on its own schedule stops being trustworthy long before the servers go dark, because exchange APIs change under it.
One reassurance if you are leaving: your coins never lived at Shrimpy. Revoking its API key at each exchange ends the relationship completely, and everything the tool managed is sitting in your own accounts, untouched.
Whatever you move to, four questions matter more than the feature list. Custody: does it work through an API key on your own exchange account, and does that key exclude withdrawal permission? A rebalancer has no use for the ability to move your coins, and should never be granted it. The sells: does it rebalance by selling winners, and are you comfortable with the taxable gains that realises? Failure mode: if the company disappears the way Shrimpy's momentum did, what stops? The answer should be “the buying stops and the coins sit still.” Coverage: does it support the exchanges and assets you actually hold?
3Commas is the fullest trading suite — deal-based DCA bots, grids, signals — but its machinery is built around opening and closing positions, not holding a passive basket at weights. It is a trader's tool. Pionex builds sixteen-odd bots, including rebalancing, into its own exchange at no subscription — with the corollary that it is an exchange, so it holds the coins. Delta or CoinStats will track a basket across exchanges very well but will not trade it; paired with a spreadsheet and a quarterly hour of manual orders, that is the cheapest honest answer and nobody sells it. And plenty of former Shrimpy users write their own rebalancing script against exchange APIs — the maintenance burden just moves to you.
Trade Leopard keeps Shrimpy's core idea — your target weights, your own exchange account, an API key that cannot withdraw — and changes when selling happens. By default nothing is sold to correct drift: new money is steered to whatever sits furthest below its target weight, so the portfolio pulls itself back toward the weights with buys, and each buy happens only when that asset clears an RSI gate you configure. A full rebalance — sell what is over target, buy what is under, in one pass — exists as well, but it runs only when you press the button, and it shows you every order before anything is placed. The one automatic sell is an optional trim that ships off and, when on, sells only profit — the proceeds sit as cash in next period's buying power and go back in through the gate on the next dip, while the principal stays invested.
Each asset in the basket can also be paused individually — buying, selling, or both — at any time. A paused asset's share of the budget is not held back: it is spent across the assets still active, and unpausing puts the asset back in the rotation. Shrimpy had no equivalent, and neither does anything that replaced it.
The honest limitations, stated plainly: it supports three exchanges — Kraken, OKX and Coinbase — not Shrimpy's thirty; it is buy-side by design, so a portfolio with no new money coming in rebalances slowly; and it publishes no backtests and claims no outperformance over threshold rebalancing or anything else. It is free. If the mechanism reads like what you wanted Shrimpy to be, the guide walks through every setting.
Effectively, yes. Bitcoin IRA announced its acquisition of Shrimpy in November 2023 and folded the technology into its own retirement-account platform. As of August 2026, shrimpy.io no longer serves a page and the app's domain does not resolve. Nothing was stranded by the shutdown — Shrimpy never held coins, so anything it managed sits in the owner's own exchange accounts.
Nothing, if the tool was built correctly. Rebalancers of this kind connect through an exchange API key and never hold coins. If the service vanishes, the automated trading stops and your assets sit untouched in your own exchange accounts. Revoking the API key at the exchange severs access at any time.
It depends on which half you used. For the passive target-weight basket: Trade Leopard does that with buy-only rebalancing on Kraken, OKX and Coinbase, and Pionex offers a rebalancing bot built into its own exchange. For active trading features Shrimpy never had, 3Commas is the fuller suite. For tracking without trading, Delta or CoinStats cover the dashboard half alone.
Yes, if money is still being added. Directing each new contribution to whatever is furthest below its target weight corrects drift with buys alone — no realised gains, no trimmed winners. It is slower than sell-based rebalancing and depends on contributions continuing, which is the trade-off. Trade Leopard works this way by default.
Every rebalancing sell of an appreciated asset realises a capital gain, and a threshold rebalancer does this repeatedly by design — it is always trimming whatever grew. Buy-only rebalancing defers those events by correcting drift with new money instead. Whether that matters for you depends on your jurisdiction and situation; this is mechanics, not tax advice.
