If you used Shrimpy

What Shrimpy was

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.

What happened to it

Bitcoin IRA acquired Shrimpy in 2022, and by the accounts of the people still watching it, independent development slowed to a crawl afterward — feature releases, exchange updates and community activity all dropped off compared to the years before. The site still runs. But a tool that trades your account on its own schedule is exactly the kind of tool you want actively maintained, 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.

What to check before trusting a replacement

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?

The options, honestly

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.

Where Trade Leopard differs

Trade Leopard keeps Shrimpy's core idea — your target weights, your own exchange account, an API key that cannot withdraw — and changes the rebalancing mechanism. 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. 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.

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 costs $15 a month. If the mechanism reads like what you wanted Shrimpy to be, the guide walks through every setting.
