## Fund Coinos server (via bitcoin-cli)
Bitcoin Regtest Mode allows us to create our own Bitcoin sandbox blockchain for use in testing & development.
From the coinos-server dir on your localfilesystem (ie- after following the 'Getting Started' section of our [root README])
```bash
docker exec -it bitcoin bash
# get an address
bitcoin-cli -regtest -rpcuser=admin1 -rpcpassword=123 getnewaddress
> bcrt1qzneawwyxe0fts5p8a6tsp4gu2mfnqzs92235hm # (example)
# mine a block to the new address
bitcoin-cli -regtest -datadir=/home/bitcoin/.bitcoin generatetoaddress 101 theaddressgeneratedabove
# verify you got the reward by doing:
bitcoin-cli -regtest -rpcuser=admin1 -rpcpassword=123 getbalance
> 50.00000000
# send 10 bitcoin to a coinos wallet account you created
# (get the address to send to from ./receive, select 'Bitcoin')
bitcoin-cli -regtest -rpcuser=admin1 -rpcpassword=123 sendtoaddress [account-address] 10
# confirm the transaction
# (do the mining command again)
bitcoin-cli -regtest -rpcuser=admin1 -rpcpassword=123 generatetoaddress 101 theoriginaladdressgeneratedabove
```
