Hehehheehe glad I could provide that info. A lot of my friends have gpu laptops but dont even use it for gaming, tears inna me eye bro. Tears. Money making machine ah!
If lets say, you're dashed a GPU laptop, youre fine, your minning rewards will be okay, but if you spend to buy, it will take a bit of time to recoup from mining rewards before you now start taking profits.
Adding external gpu is cool, but you will need cooling fan too or does it come with?
Personally, I'd rather stake that 240$ on Hive or lend it on Compound on Ethereum or risk it like @belemo and stake Vite tokens instead.
As for the electricity, i wouldn't advice a generator because of fuel, what most do is installing a solar panel that has battery, - which u will dedicate to your rig so it can last. Its more cost effecient than generator.
Because you need to have zero down time as much as possible, so you need steady internet. You see sey cost don increase like that.
If you dont have the luxury of steady electricity, internet and equipment, staking is a better option.
Man the cost implication is really demoralising. Too many uncertainties
