Per lbryio/lbrycrd#307 (comment), the min vout value will be 3000 dewies in the next lbrycrd release (this was later updated to 1000 dewies). Today, torba produces transactions with very small vouts that may not get processed by all miners, and thus, stuck in the mempool.

When creating txs, torba should consider this min amount to ensure there's no vout that's lower than it.
