i think for the gpu's laptop technology doesn't same as gpu for desktop, they have reduce the gpu's tech to reduce power consumption and heat problem. but some of altcoins are still mineable and makes profit when their price are going up, so at least you have to choose the right coins to mining, in order not wasting your time and money(for pay the electricity). If you mention vertcoin, there is possibility this coin will stay longer, as we can examine from the market price and their lifetime, its going up, although nowadays fluctuate, but never too far.
