Since CoinLenders is known to maintain cash reserves sufficient to cover only a fraction of its obligations to depositors, a number on a CoinLenders screen is not quite the same as receiving cash. Can you say whether distributions via CoinLenders will be ring-fenced so as to be available to participants for immediate withdrawal as actual cash? Or will distributions be pooled with other CoinLenders reserves, implying that the availability of actual cash will depend on how many other people are already attempting to withdraw from CoinLenders at any given time?
For the first few days of a liquidation payment, yes. It is an unwise idea to store significant amounts of BTC on internet facing servers for security reasons.
The question isn't about storing significant amounts of BTC on internet facing servers for security reasons. (Although if it
were only about security and nothing more, then folks might ask why it would be the case that CoinLenders can only cover a fraction of its obligations to depositors at any one time, while Inputs.io does not have any such limitation -- or do you mean to say that Inputs.io is also unable to cover all its obligations to account holders at one time?)
Rather, the question is about the actual cash on hand (anywhere, in cold storage or otherwise) to pay depositors and how quickly depositors can expect to receive actual cash. If it were merely a matter of not storing large amounts of BTC on an internet facing server, nobody would worry about a delay of a couple of minutes to refill a hot wallet (not that CoinLenders has a normal hot wallet anyway, since it does not use the blockchain). Some, though, might wonder about how many
days it could take to retrieve their cash, given that CoinLenders may not have the cash on hand
anywhere, including in quickly retrievable cold storage.
As you know, this is not a theoretical question: CoinLenders has run out of cash to cover its deposits in the past and had to halt withdrawals for a couple of days. I'm simply asking about the extent to which distributions made from liquidation of the fund via CoinLenders accounts will be backed by actual cash versus soon-to-be cash. It would be wrong to characterise that question as having anything at all to do with "security reasons": cash is cash, whether it is sitting on a server or in cold storage.
