Searching for a bitcoin lottery mining opportunity

Hey everyone

If it is unprofitable for you to buy an ASIC because of noise or expensive electricity, then USB miners can be used with Raspberry Pi and other mini PCs. I think that when preparing the place it will be completely safe and not consume a lot of electricity, but your chances are also minimal. But any device is not eternal.

Couple of options 1) Apollo BTC: https://shop.futurebit.io/collections/all 2) Find a used S9 and mod it a bit: https://bitcointalk.org/index.php?topic=5160194.0 3) Something like a heatbit: https://heatbit.com/      or    https://www.ebay.com/itm/266071039921 Keep in mind there is a 99.9999% chance you are going to loose money. The cost to buy it, the cost to run it, are all going to be there. If years later you never find a block. It's money that is spent and never coming back. But....as you are looking to lottery mine, I am thinking you know that already, just wanted it out there in case someone else sees this. -Dave

True, with a but. There are a lot of videos showing the disassembly of it. They are just S9 units in a custom case with a custom fan assembly looped through a custom wireless bridge. You can flash other firmware and a few other things to get out of their NH only setup. I really would not want to, but it is always an option. Probably should have mentioned that in the reply I made. The other option for lottery mining is also really old miners. With a little looking you can find MANY generation out units at places like thrift stores and pawn shops and such for less then the scrap metal value at this point. I picked up a pair of S7 units this spring for $5. The boards and aluminum heat-sinks were worth more then that. Put together a complete one from the both of them. Scrapped the other and have a 4th unit when running on low power just about silent mode. Unlike the S9 mod I mentioned before these would be cheaper to buy money wise but take more time in hunting one down. -Dave

Sure check this again before getting your hands into the game,if not for anything  remember  "THE COST OF MAINTENANCE ".  He already gave you a choice just make sure you choose wisely

Since u are gonna use the machine for lottery than you can pick any device with your criteria on ebay but like Dave said it will 99.99% give u unprofitable for anything straight from your buy and operating it. and keep in mind that you need to pay the electricity bill every month unless you have free electricity

Wow man the heater come miner? I am seeing this for the first time and love the idea. I love the ideology behind it but I am really not sure about the calculations that they have shown on the website. They are claiming that over the period of one year one Heatbit device can generate up to $980 that is just insane and doesn't add up with the mining profitability calculator. According to CoinWarz, the current profitability can only happen if we have over 100 TH/s of hashing rate with average electricity rate of around $3.00 The device only produces 10 TH/s of energy and cost around 300 USD. It would take forever to get my ROI with this type of device. Either they need to upgrade the Mining Chip to Hi-end processing power or this idea or device is just cool for project purpose. Though HeatBit is considering the average price of three years, I highly doubt we have profits. We do not know the future of Bitcoin. It's volatility can either bless you or take everything away from you.

I remember seeing a thread about it in the past. Not that old so you can visit that thread and see other people's comments about the product. I guess you can argue that it is one of the lottery miner products, although from their advertisement they don't seem to think that way. You should not expect consistent profit from a product like this, stick to the old and tested ASIC or other mining rigs if that's what you're looking for imo.

Maybe you could try with some old Antminer S9 miners. If you want to chase a jackpot those ones are a good option, I just saw a seller in my local market who offers 10 units for $1,790, maybe you could buy 5 units and make solo mining in the pools that allow solo. I'm not sure if this is a good idea because there is the chance that you never hit a block and you will have to pay that 1100W energy consumption from the miner for life, that isn't cheap at all.

And why don't these sellers themselves use ASICs to mine bitcoin in solo? In Russia, you buy 10 of these ASICs for a maximum of $500, and this will be the price with delivery. But these ASICs will not be in good condition after several years of mining and storage in warehouses.

Me too, if anybody is willing to sell please do send some quotes to seema.bhagare@ketto.org. Also looking to invest money in crypto currency

Where are you located? I have a silent miner, 7TH, 600W aprox. A modded version of an Avalon 821 I guess it is

its good choice

mining with an s9 to win a block is just plain dumb. Mine with an L3+ to win a block of doge. and if that does not float your boat. mine the L3+ to nicehash and when it pays enough btc to cash take that btc and rent at nice hash pointing to solockpool the L3+ earns 75-90 cents a day pre power cost the s9 earns 84 cents a day pre power costs. seems the same but the l3+ burns 625 watts and the s9 burns 1250 watts. see below burns 600 watts and is quiet so 14-15 kwatts a day I go for a block of doge but if you do nicehash and stack 80-90 cents of btc a day in a month you can rent and  point it  to ck pool solo to mine for a btc block the doge solo pool address is stratum+tcp://doge.zsolo.bid:8057 if you decide to go for a doge block and not do the multi-step mining for the btc block

Phil, some btc maximalists will probably report your post for talking too much "alts" personally I find your argument completely valid, mining is essentially a process of turning electricity into value, we all probably want just bitcoin but if there is a way to get more btc mining something else then why not.?

You can take a closer look at the GekkoScience USB asic miner, which can be purchased separately, for example, Newpac 90 Gh /s for $100, and in the proposed configurations indicated on their website as part of several devices with installed fans and a usb hub. https://gekkoscience.org/product/gekkoscience-newpac-dual-bm1387-usb-stickminer-90-gh-s https://gekkoscience.org/product/6-x-gekkoscience-compac-f-1-6th-s Edit: it turns out that the gekkoscience.org site is actually caught scamming users, so be careful, thanks to @kano for pointing this out, the gekkoscience.org scam thread is here: https://bitcointalk.org/index.php? topic=5436634.0

take a look at the Bitaxe by skot. Its open source and a new version uses the BM1366 chip that are used in the S19XPs!

got a link for this?

There you go https://bitcointalk.org/index.php?topic=5460574.0 And this one is the DIY for BM1397 chip, https://d-central.tech/product/bitaxe-diy-kit/ The concept is rather interesting, If you have the time take a look at this DIY video https://www.youtube.com/watch?v=vS_Gs5xYmRk , you can learn how to build the thing yourself, great for a learning experience, I wonder if anyone here has tried to do that.

I believe the gekkoscience website is a scamsite. They don't have a website. The usb-miners are sold with resellers. please remove the links
