again still not sure on how to proceed.
A friend and I we have $150 + $150 available for BTCD
Which is wiser?
pay $300 for 15mh/s hashlet for 12 months and convert btc to btcd (probably on a daily basis)
or buy around 50 BTCD directly?
first option will have to ROI first
Buy BTCD. Don't waste your money on a miner, as time goes on, that 15 mh/s will make next to nothing. Take a look at some mining calculators, you'll actually start loosing money a few months down the line.
Don't forget, you'll need to earn your initial investment of $300 back before you even make any money. Compare that to the steady 5%+/-~ BTCD was making.
