Practically I’d say 1M sats, depending on fee environment 

 Hmm perfect thank you. Asking because I’d like to pick up one of the start units and pay in btc 

 Over 3m sats IMO  

 🤔🤘🏼 

 totally depends on your node's liquidity. Often people use 3rd party services and thus aren't able to know what liquidity the node of their provider has. For my node, I could receive a maximum of ~1.9 million sats in a single payment, but 1 million would be much more reasonable.

With current fees on-chain being low, I would probably send anything 500k sats or more on-chain if I had the option. 

 Perfect thanks fam!
