Thank you Stephen. So, a transaction with 200 outputs would be okay, right? :-)

That's no problem at all. I expect such a transaction to be around 7 KiB, unless you need a large amount of inputs.

<p>I am building a web-app that needs to send money to different customer's addresses. I would like to minimize transaction costs and avoid unnecesary traffic, therefore I would like to pay all of them at the same time. <strong>How many different destinations can one single transaction have?</strong></p>

<p>Cheers!</p>
