I guess its strategically better to wait until waves ico is over...
There are new ICO coins popping up left and right. If Lisk waits, another coin will pop up. Best to just launch when ready.
We aren't taking into consideration other ICO's or coins, the team is focused on building a reliable platform. When it's ready, we will schedule a specific date

Max, Oliver, Joel, care to share ideas for launch date and new network fees?
Launch date will be specified as we inch closer to the end of April (if we feel everything is ready). The fees will get adjusted, it's just a matter of figuring out the perfect balance.
