100 BTC sounds like enough Smiley Another thing, since you mentioned security, what do you think about using hardware wallets to store funds instead storing them on exchange's wallet? I know a lot of decentralized exchanges implements this kind of solution and I wonder if this could be even possible on STeX
We use cold wallets to store most of the funds. With hardware wallet we cannot control and confirm the security level and do not want rely on someone's else professionalism in this critical part. Properly configured server is unpenetrateable, all exchanges' hacks has inside or human stupidity behind. We use same encryption level as bitcoin blockchain itself and similar principle of confirmation for the transactions.
