Of the people I've spoken to, their main concern is that LakeBTC (and LakeBanker) are based in the PRC. I think they're worried (whether it's valid or not) that the Chinese government may one day crack down on token sales, or introduce a new regulation that makes the platform non-usable. Similar to how China has slowed down the growth of Bitcoin exchanges by limiting bank transfers in and out.
What would you say to reassure them? Alternatively, are there any actual advantages to being based in China over other countries?
