We are definitely aware of such a potential issue, it's true that at some point low amount orders can/will end up being dust. We are therefore working on the following solutions:
- increase the minimum buy amount (currently 25 CHF/EUR)
- updated the referral program not to send too small earnings to the user's wallet (only once user accumulated 10 CHF/EUR)
- working on a solution to encourage users to consolidate: it's more tricky than it sounds as we have a lot of newbies as users
- moving to lightning: we recently released our non-custodial lightning wallet and we'll keep improving from here on to also provide buy/sell orders to lightning directly
