Oh so now you're changing the story to how he manages to cool off 69 GPUs in a garage? That's total bull, sorry. Even if you used no lights, microwave, phone, PCs/laptops/tablets, refrigerator, etc. and dedicated 100% to GPUs, there is no freaking way a regular residential line can power that. You'd have to put in a work order for $10k+ to get that much power, and likely it would be too much for your local distribution so you might have to get them to upgrade your local infrastructure which costs tens of thousands of dollars. The alternative is to rent something C&I with lots of amps, preferably 230V for higher efficiency, or server space or something like that, which also costs a lot.
I am willing to bet you a bitcoin that your insurance company would deny your claim if it found out you had 69 GPUs in your garage or whatever. Insurance companies try to wriggle out of paying up whenever possible. And then there's the liability/lawsuits you face from your neighbors in a worst-case scenario.
So your worst-case mining scenario is taking out your neighborhood and going bankrupt, if you were crazy enough to mine with 69 GPUs in your garage rather than rent a brick warehouse or something.
Even if you don't suffer catastrophe like that, if LTC goes to zero then the value of your CPUs, mobos, RAM, PSUs, video cards, etc. will also take a HUGE hit as all the mining equipment floods the market, so it's not THAT much protection to mine rather than buy coins. In the meantime, the power bills, rent, etc. all need to be paid if you mine. So you can find yourself in a situation where you spent $50k on mining equipment, $50k on power, and then LTC goes to zero after a year. You then resell the equipment for, say, $20k since only the GPUs and PSUs are really worth that much in bulk, and the GPUs will have depreciated over the course of a year and hard wear-and-tear. You ate $50k in power bills. So you lost $80k overall.
Whereas if you bough $100k of coins the most you can lose is $100k, which is very similar to $80k. Your worst-case direct purchase scenario is losing whatever money you put in. That's it. You can't lose more than you put in. No risk of catastrophic fire or anything, and no effort like making sure all the rigs are up, software updated, making sure no PSU is about to blow, etc.
If it were that easy to mine with 69 GPUs why don't YOU do it? Yeah, exactly. That's why most people don't mine with that many GPUs, it's not worth it.
Perhaps... but the risk with buying coins directly, especially when they are a few bucks or less than a buck each, is a lot greater than investing into hardware which you can still have a use for or sell with minor depreciation.
I already wrote about the risk thing a few posts ago, said for small scale miners buying stuff they would have bought anyway, it might be more of a risk hedge. But 69 GPUs?? That's a LOT of risk, and if you're such a true believer in a coin, you might as well just directly buy some and save yourself the headache. That's all I'm saying. 69 GPUs? :shakes head: You could simply direct-invest and skip the headaches. But don't invest more than you can afford to lose.
