You can still mine ETC on that laptop of yours, 4gb is doable today compare to weeks back, I can bet something around 4$ from ETC with a gtx1650 right now, the truth is this insane amount of profits won't last forever, I can smell bear market coming already
Not sure about $4, more like $2 or less on ETC. Not worth burning an expensive laptop for it.
Mining ERG is more profitable than ETC and more than ETH also
You can also mine ERG+ZIL for more profit.
There are so many alternatives out.
