good to hear. hope they invest in good security. i use them mostly like a gateway to get my usd turned into bitcoin. it usually never stays there long since i will send it to either an exchange, or to bitmain, or to my cold storage wallet. i have never turned any bitcoins into usd so i don't know how that works but i assume is same as buying it.
Yeah I have not used that USD wallet they just put into place. IMO, you should never store money there ( or anywhere for that matter ) at least for the time being....cuz you never know.
good policy. stay with it. think security all the time. only keep on the exchange what you can afford to lose. that is another reason why i do not advise peeps to buy bitcoins is due to the security problems and that i would have to teach them how to use cold storage. i tell people to be very conservative and only buy what can afford to lose. if can't handle those requirements then is best to buy pms (gold and silver).
