Someone asked about this, so I might as well write it down.
How do Bitcoin and Ethereum differ in the way they keep track of transactions?
As I understand it, each time an Ethereum externally owned account sends a transaction, its nonce increases by 1. Transactions must be executed in nonce order, and each nonce can only take effect once.
$BTC uses the UTXO model. The balance shown in a wallet is actually the sum of many unspent outputs.
Keep your position size within your means and leave yourself some room.
