You can go to Hash-To-Coins mining pool where all the coins are mined using scrypt algo and mine some of the lower priced coins such as DGB which has a price of about $0.06 right now. With just one Moonlander2 running at 4.5 Mhz, basing electricity costs at $0.10 /Kwh, and 7 watts draw you can mine about 3 DGB coins a day. Every week, about 21 or so, and every month about 92 coins.

That is not much money at all however if you think in terms of coin accumulation instead of immediate gains, if that coin was to go to $0.10 from the current $0.06 then you have made a little bit of money and nearly cut your ROI in half (an easily seeable gain from 6 cents to 10 cents). Now if the coin went up a great amount (I can still remember holding BTC when it was sub $100.00) then you could have a small windfall just at $10.00 a coin. I don't think for a minute it will jump up like that but stranger things have happened.

Just pick your longshot altcoin from those mineable with scrypt off the page, direct you miner to get to work and give it time. What do you have to lose? The price of the electricity?
