I was thinking...we could lower the amount of time coins stay "staked" I forget how many blocks it is for POT but it is quite a few hours. Maybe we lower it? Unfortunately this type of change would require a hard fork.
I am not intimately familiar with the inner workings of posv so this is just an idea from someone who should probably stay quite.
The maturity time for coins that stay "staked" before they be can spent is a security issue, if you have it too low it makes it easier for an attack on the network. You see this with every coin BTC included. There is a waiting period from new coins are generated to when they can be spent.
I will have to double check but for potcoin I think its about 2 hours from when you stake to when those coins are available to be spent. We had this discussion months ago from a merchants POV, people were arguing against POS for merchants because they wouldn't be able to spend those funds for a small amount of time. Those people either have issues with common sense or they have never worked with cash at a business, IE, being the one who deals with funds incoming from customers as well as being the one who makes the bank deposits.
