this requires trust in delegates, the exchanges is rarely trusted to them, so increased deposit time to 2 hours, only on the Hitbtc deposit in 6 minutes so.  A high hashrate is preferable to trust.  But many coins do not have a hashrate, but they are credited quickly, I do not understand the logic of exchanges. Why do bad coins without hashrate has a good grow but a good Komodo has bad grow?  Why Komodo block in 1 minute, it is fit for neither Dex nor for shopping in the stores, why not do a hulf second like the EOS? Even 15 seconds of ETH is a lot for Dex, I think that's the only reason EOS is a leader. People otherwise understand the high speed of transactions, give them what they like
