How many confirmations for SPDR before the coins are on the exchange?
We made a system, which change conf number for low hashrate coins in auto mode.
It is just security measure to prevent (or at least to minimize) attacks on coin net.
Currently, 125 for SPDR.

But how do you calculate the confirmations required for pure PoS+MN blockchains?
For example you require 125 confirmations on Zenzo, with 1 minute blocktime that's 2 hours wait time!
With the supply in circulation and the current price, it'd cost someone 148000$ to attack the coin with a 51%, so don't you think that's at least secure enough to drop the confirmation time to about half of what it is now?
Semi-dead PoW coins are easily attacked if you point Nicehash or a small farm or a couple of ASICs on their network, those are really easy to attack (though pointless profit-wise).
