-A solution in your space is badly needed. Fund administrators really need an option that is better than cointracking.info and coinigy. A lot of these folks are looking at partnering with Libra here in the near future.
-your offering as is, is too limited. anyone investing seriously in the space owns a lot more than than the 4 coins available in your wallet option.
-Most could probably get by with the exchanges you have listed so that's a a good thing
I know you're just getting started, so I'm excited to see how your offering progresses. Good luck, and happy to talk more offline. Would also be interested in investing. Thanks.
