You can already deposit the two altcoins that you mention.
However, at the moment you have to exchange them using
the exchange markets at Fairlay.
This isn´t really a problem as they have a pretty low vig/juice and
therefore you get a reasonable exchange rate when trading your altcoins
for BTC.
I would prefer to avoid exchanging at all. Seems like something easy to implement on their end (keeping client funds in whatever alt-coin was used to deposit), and I hope they consider doing so soon.
Hi, we are not very active during the holiday season. So support requests might take a bit longer. Thanks for your patience.
Back to your idea. We are planning to implement BTC lending (with fees very close to zero). You will be able to deposit for example 8 BCH and use that as collateral to receive a loan of up to 1 BTC. If you are not losing these BTCs permanently you never have to touch BTC to use Fairlay.
