vertcoin seems promising for nvidia gpus, and the VTC price looks due for a rally (it barely twitced during the ethereum/alt rally back in janruary)
GTX 1070 ($500) appears to be capable of making $3/day mining vertcoin, and the difficulty has been fairly stable for months in that currency. seems reasonable to think you could mine back the cost of the GPU witin a year, and still have a $300+ resale value as its the most recent Nvidia seies. IMO a 50% profit for a year of mining, using high-value cards, seems better tan piling in the $300 RX480s on an algorithm with a difficulty spiraling out of control
i would say $400 resell value, those thing are brand new, they will not tank at all in value for at least 6 months, and surely not below $400 in one year, that is their price target after all
so you practically need to roi on $100, which is a joke
resale value is never >75% BNIB price, realistically closer to 50%. but still reasonable ROI within a year, on a card that could run 2+ years easily
that's depend on the time, if you sell it now, it's still above $400 easily, if you sell it in one year, around $350 will be a correct price
i sold my two years old 970 for 60% of its value, but it was two years, so 50% is the absolute minimum at which you can sell it
Its impossible to tell what a GPU will be worth after ETH goes POS.
During the Litecoin crash, there were $400 GPUS going for $150 a few months later.
All these Neoscrypt/Vertcoin will get murdered once 250,000 GPUS from ETH start hammering those coins.
Even these $500 Nvidia cards will suffer also. When ETH goes POS your 1070/1080 will NOT be selling for 80% retail on eBay.
Gamers will rather buy 2x 480 and crossfire then buy one 1080.
If you want proof look at the difficulty charts for SIA and LBRY for the last few days. As soon as those coins were profitable it took mere hours for them to match the profitability of ETH. This is an example of what will happen when ETH is no longer profitable to mine. Miners are crazy greedy and switch algos like crazy to maximize profits.
The only coins you should be concentrating on are
1) Bitcoins - Buy some cheap S7 and undervolt
2) Etherium - Until it goes POS
3) Litecoin/Scrypt - ASIC very expensive
4) X11 - ASIC very expensive also.
Everything else is only profitable short term and shouldn't be judged by a decision whether to buy a particular GPU or not. The miners reward for Vertcoin, Featercoin, LBRY, are a small percentage to the miners reward for BTC/ETH/LTC.
i sell it privately and i only remove VAT from the resale value, and always worked for me, i can bet what you want that i'll be able to sell my 1070 in case this place die for no less than 70-75% within 6 months
