but he payed for what is said in proposal. so if he needs to pay for something with bitcoin, moves the HBD to the exchange, he already has 1 btc of personal funds there, so now he has 1.1 BTC. he pays 0.1 BTC for something from the proposal. than he transfers 0.1 BTC to HBD and back to the account and stakes it. Is that ok?

Or here is a personal situation. i went to help and document the WRC event. it was kinda a last minute thing, i didn't even think about should i get payed. now there is a chance that i will get some HBD for 1000km of fuel and tolls i paid with my own money. is it ok if i stake that HBD?
