a) Most likely not going to happen. Don't think its really feasible due to the fees required sending small amounts of extremely new coins to hundreds/thousands of users, we'd ask to send you 1 coin, and we'd be paying half of that in fees. Obviously that depends on hashrate somewhat, but its a very high amount typically.
b) This doesn't really make sense. All that matters is the price at the time that you get them (and even that doesn't really matter). When you get the coins, either you'll decide to hold them for a time period because you think the price is going to go up, or you'll decide to sell them immediately because you think the price will go down. What the switcher decided doesn't matter, the coins are already mined and is essentially a sunk-cost. You decide if you think price is going up or down, and make a decision based on that, and that alone.
Got that. But please, note that:
a) Let's forget the idea that you'll be paying out in every possible coin. LTC and DOGE would suffice.I am also saying that you could trade some coins also for LTCs - if that's possible. Anyhow - pressure on BTC must be eased somehow. BTW, you could put some minimum amounts to be paid in other coins.
b) I am sensing troubles in your thinking. You're switching all the time - to catch the most profitable coin. The most profitable means 'profitable' all the way to my wallet.
So for example, if some pump starts on some coin - you decide to mine it - when coins are mature - the pump is over - and dump starts. You're calculating 'profitability' - but in reality, coins are not exchanged near that figure - which was a deciding factor after all.
There is a new feature I'd like to see at PW. This feature was available at 'middlecoin'. That was a graph - which stayed at zero (0) if coins were sold for the price for which were coins mined. The graph went up - if coins were sold even at higher price and it went under zero - if coins were sold under the mining price.
Blackcoin payout would be a great option!
