		<p>Remote node can be used by people who, for their own reasons (usually because of hardware requirements, disk space, or technical abilities), cannot/don't want to run their own node and prefer to relay on one publicly available on the Monero network.</p>
		<p>Using an open node will allow to make a transaction instantaneously, without the need to download the blockchain and sync to the Monero network first, but at the cost of the control over your privacy. the <strong>Monero community suggests to always run your own node</strong> to obtain the maximum possible privacy and to help decentralize the network.</p>
