# Enable or disable coins

> Add a coin to BasicSwap or switch one off with basicswap-prepare's --addcoin and --disablecoin, using Docker, the basicswap-bash scripts or a source install.

A new BasicSwap runs Particl, which it needs for itself, plus the coins you chose when you installed. You can add more coins, or switch one off, at any time. Adding a coin downloads its daemon and creates its wallet from your existing recovery phrase, so it needs no new backup. Disabling a coin stops its daemon but keeps its data, so you can turn it back on later without syncing from the start.

Every change follows the same pattern, in which you stop BasicSwap, run the command once for each coin and then start BasicSwap again. The coin names to use are `bitcoin`, `litecoin`, `monero`, `wownero`, `bitcoincash`, `dogecoin`, `namecoin`, `decred`, `dash`, `pivx` and `firo`, while Particl always stays on.

## Enable a coin

**basicswap-bash**

With BasicSwap stopped, run the add-coin command:

```bash
bsx-addcoin
```

It lists the coins you can add and asks which one you want. For Bitcoin and Litecoin it also asks whether to use an [Electrum light wallet](https://basicswapdex.com/docs/user-guides/lightweight-modes) and, for a full Bitcoin node, whether to start from a snapshot, while for other coins it offers to connect to a node you already run. When it's done, start BasicSwap again with `basicswap-bash`.

**Docker**

In the `basicswap/docker` folder, stop BasicSwap, add the coin and start it again:

```bash
docker-compose stop
docker-compose run --rm swapclient basicswap-prepare --datadir=/coindata --addcoin=bitcoin --usebtcfastsync
docker-compose up
```

**From source**

With BasicSwap stopped, set up the terminal, add the coin and start BasicSwap again:

```bash
export SWAP_DATADIR=$HOME/coinswaps
. $SWAP_DATADIR/venv/bin/activate
basicswap-prepare --datadir=$SWAP_DATADIR --addcoin=bitcoin --usebtcfastsync
basicswap-run --datadir=$SWAP_DATADIR
```

Replace `bitcoin` with the coin you want, and leave out `--usebtcfastsync` for any other coin, where it does nothing. A few more options change how the new coin runs:

- `--btc-mode=electrum` or `--ltc-mode=electrum` adds Bitcoin or Litecoin as an [Electrum light wallet](https://basicswapdex.com/docs/user-guides/lightweight-modes) instead of a full node.
- For Monero or Wownero, you choose a remote node with the environment variables that [Prepare options](https://basicswapdex.com/docs/user-guides/prepare-options#light-wallets-and-remote-nodes) lists.
- If your wallets are encrypted, give the password as `WALLET_ENCRYPTION_PWD`, for example `docker-compose run --rm -e WALLET_ENCRYPTION_PWD=yourpassword swapclient basicswap-prepare …`, or `WALLET_ENCRYPTION_PWD=yourpassword basicswap-prepare …` from source.

**Reusing a pruned Bitcoin chain**

If you already have a pruned Bitcoin blockchain, you can copy its data folder into BasicSwap's `bitcoin` folder, which is `~/coinswaps/bitcoin` or `/var/data/coinswaps/bitcoin` with Docker, after adding the coin, and skip most of the sync. Leave out its `bitcoin.conf` and any wallets, and remove wallets that were copied over, or the Bitcoin daemon won't start.

The new coin then syncs its blockchain, which you can follow on the [Wallets page](https://basicswapdex.com/docs/user-guides/manage-enabled-coins).

## Disable a coin

**basicswap-bash**

With BasicSwap stopped, run `bsx-removecoin`, enter the coin's name, then start BasicSwap again with `basicswap-bash`.

**Docker**

```bash
docker-compose stop
docker-compose run --rm swapclient basicswap-prepare --datadir=/coindata --disablecoin=bitcoin
docker-compose up
```

**From source**

```bash
export SWAP_DATADIR=$HOME/coinswaps
. $SWAP_DATADIR/venv/bin/activate
basicswap-prepare --datadir=$SWAP_DATADIR --disablecoin=bitcoin
basicswap-run --datadir=$SWAP_DATADIR
```

A disabled coin comes back on when you enable it again in the same way as above.
