You'll be able to buy it through the exchange, directly from Triaconta's bot that will buy new underlying assets.
But yeah, might be a good option to still keep the direct (SEPA) deposit open, for people that don't want to bother with exchanges.
Yeah, that's actually a fair point. I'll come back to you with an answer, need to discuss.
You could simply have a higher minimum deposit (maybe 1000 euro), and maybe even a higher handling fee, to cover the hassle of dealing with deposits.
Another note: I know the main idea for Triaconta is to have your bots generate revenue. But I think the concept of offering these funds is a big thing in this space. It's very surprising to me that not more players are offering it at this moment, so I think you guys have an opportunity there in the near future to capture that demand...
I think you could easily have a portfolio of 3 to 5 different index funds, and maybe charge a low holding fee (say 1-2%) to cover expenses and to reward TRIA holders.
I think a top-10 or top-20 funds, weighted by market cap, would attract a lot of people...
