If the PoS reward for Lv1 and Lv2 coins decreases over time... I'm assuming it would be best to hold Lv1 coins for a while before burning them (initially) as they will have low coinage and thus generate Lv1 coins faster than if they were older.

Once a certain point has been reached, I assume burning them to Lv2 would then be far more beneficial as they no longer generate very many Lv1 coins by themselves...

Do you have more information on the rate of decay of the PoS from Lv1 and Lv2 coins? 100% ROI in 1 year from Lv2, and then what's the rate? Approx 1,000 coins in a year, 1,250 coins in 2 years? 1,300 in 3 ... etc.

Thanks.
