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.
just make sure you sell as you go that erg coin cause once this crypto market crashes to hehell, those altcoins will suffer a lot, most likely will lose 99.9% of their value today.
