Playing with hardware is much safer than playing the market, you'll never lose 80% of the value on your GPUs over night, but Bitcoin can go back to $1000-2000 in matter of hours though.
Holding isn't 'playing the market'.
So curiously, you guys DO realize that when you mine coins that's directly tied to market value right? Every time you mine a coin, it is directly connected to the value of the market. If it goes up or down before you sell, you lose or gain money. You area already playing the market you just don't know it. Just because you sell immediately doesn't mean you are immune to market fluctuations. One of the reasons we're making $3 per 1070 IS because BTC has increased in value. If it didn't, the amount of money you're making would more then likely not increase (there are very, very, very few coins that will move against BTC and when they do it's temporary).
So if BTC crashes and burn, so will your daily profits. Mining isn't like this magically safe sanctum of guaranteed profit. It is literally, directly tied to market value.
1) The thing is YOU DIDN'T MAKE 3.5 ROI! That's what we're talking about you silly goose. You aren't earning $7.5 a day per 1070. Like you just will numbers out of your ass and go 'nuh uh'. The whole reason I brought it up is because we AREN'T making that sort of money and it's more profitable holding BTC then investing it in mining hardware.
2) Why did you magically make an extra 5k in five months?
3) Your numbers don't even make sense. Jesus...
4) LOL hardware doesn't increase in value, it depreciates. And no, the prices of GPUs have relatively returned to the original values so they aren't artificially worth more (nor would you sell them right now anyway).
5) When you would sell them, your quoted 'five years' down the line they'll be worth about $70 a piece.
I understand that it's hard to believe or simply understand but:
1) It's simple - I did. The recipy for today was simple SIGT(~1BTC), BTX (~2.5BTC), XSH(0.8BTC) and several others less profitable. 0.8BTC of XSH was mined by ~15*1070 for 2 days. ~0.3BTC(part of the total SIGT) was mined by 2*1080 by 1 night with the shittest sgminer that made less than 8Mh on 1060. 10K in GPUs made around 5.5BTC in total for 6months. Some were cashed out. Some remains in coins. If I wouldn't cash some BTC earlier - it would be ~60K at current price.
2) It's simple - price of coins change every day.
3) Yes - these numbers doesn't make sense for nichehash/zpool&yaap's/ethereum/zec/xmr and others mining and cashing out imediately. For most of those who mine only with x$/day in mind they don't make sense.
4) 1060/6 just before June pump cost <200Euro. You can check the price today. So even used they still cost +/- the same or even more - it's hard to find Samsung memory in 1060 nowadays.
5) Actually I don't care whether I would sell them or not in five years. I think in a year I can throw them in a trash and buy new generation of GPU's.
I'm not going over your convoluted numbers (like right off the bat I see you multiplying profits months ago as if you held?!? when you've been saying exactly the opposite that for your entire argument), but I can 100% guarantee that you didn't make 3x ROI in five months. Some of those coins were good for a little bit, that only lasted a couple days though, as I've mentioned. When I talk about 56% growth, that's over the entire month. Not one day of good profits.
Yes they do change every day, as does the price of BTC. No shit, that's literally what I've been talking about and how that increase has been more profitable then directly mining.
I don't use Nicehash. I said $2.5 a day because that's about the average per public (not super niche coins) that you can earn for a 1070 over the last month. That takes into account coin price fluctuations. Also not sure why you weed out ZEC/XMR/Ethereum, matter of a fact Cryptonight is one of the top earning algos right now as far as GPU mining goes. You really have no idea what you're talking about.
Memory types only really matters for mining Ethereum and even then if you adjust timings on cards it doesn't matter much. Not even sure why you're talking about the price of a 1060 and how it relates to the argument.
You were originally talking about resale value of your cards and how they're worth money. You once again have no idea what you're talking about and just randomly throw out parts of your argument after it's been disproven. The whole reason I'm talking about it is because you mentioned your amazing appreciation of your GPUs. XD
No, there isn't a 'pluses', you have to BUY hardware and it's not easily liquidable. Furthermore you would be earning a lot more then that this month considering (as of the original post) increased in value 56%.
Your problem is that you don't understand main plus of hardware. You can MINE coins that you can't buy. You can mine them first, mine before someone will be able to buy them. And you can mine them a LOT. You can mine dozens of such shitcoins. XSH - definite shitcoin - pumped = 0.8BTC for 2 days of 15*1070.
3$*15GPU*30days = 1350$
0,8BTC = 9200$
So my 15*1070 can earn nothing in the nearest 6months and still will be more profitable than niceminers.
And you just stepped into the realm of extreme prospecting. That's even more volatile and more luck based then playing markets with low volume amounts. You try to make a argument for consistentcy while mining and then go talking about mining coins that have absolutely no value. For every coin that you've been able to mine before they even come out there are dozens upon dozens that are absolute garbage and have went absolutely no where.
You can buy a lottery ticket and win the lottery tomorrow. That has no place in a discussion of stats and economics. Matter of a fact I bought a coin yesterday and it's 100000000000x times in value! I made so much money, te-herp. See how that works? You can do the same thing without using mining hardware.
You can mine dozens of such shitcoins.
then you get a shitload of coins.. You can become a crypto billionaire with just a few rigs in this klondyke...
Yup, everyone will become a billionaire in these five easy steps.
. Yes, only niche coins can make you x10-x100 profit. You won't be able to make it with eth/zec/xmr etc top coins nowadays. For last month - average profit for not niche coins - was 3-4$ per 1070. Thats your lack of knowledge that leads you to 2.5$. So - mine zec and be happy.
