Is 20 Xrp Need To When Using Nano Ledger S?

I have experience with accounting and understand your point. But… If you max out an exchange before going through Poloniex, I find its a little counterproductive. You don’t know how many trades they have or what exact valuations they can quote or even how many LTC (or BTC) is on the books. It seems like the seller could be trying to “cook his books” by having nearly an entire number of coins listed as sold at one price but unavailable for purchase w/o actually selling them, which would make it look like he was lying about having more xrp than available (to the other party). I hate to think that this is what happened with Poloniex sellers or customers for that matter – but if it’s not few were reporting problems getting there coin after their trade took place. It looks fishy to me too
