Anyone know where I can get ahold of price history database for every coin, for the entire history?

Thinking about writing my own software to calculate my taxes.

In case anyone lives near me.  Selling in person for $530, what I paid for the card 1 month ago.

I meant to post this in Mining (Altcoins) -- sigh.

What was the original bitcoin wallet?  Can I still download the source code and compile it ?

I think that's the one I wanna go with.

Is silver a good idea to buy now?

I want to sell 5 x 1070 TI.   But I am worried if I sell them on ebay I might get scammed by a buyer.  I'd sell them individually and spaced apart a couple hours to make sure I don't get the same buyer.  What are the chances I could lose a lot of money?  If I video myself showing the card put in box at the UPS store and handed over to clerk, should that be enough evidence to show ebay to prove I mailed what I promised?  I have 100% feedback over the past few years.  HOw much does ebay do to protect the sellers?  Do they insure against this?  They make enough commisions on the sales it seems like they should protect the sellers as well no?

Sorry I know this is slightly off topic:

Is it a steal to purchase them now or should I give it more time?  I can buy most stocks at around a 10% discount

I was thinking of using the Robinhood app since they dont' charge fees and do like $100 a month for long term retirement investment.  Dollar cost averaging.

Or is it a gigantic bubble about to burst again?  I got burned bad in late nineties when bubble burst!

Cant' do a thing on binance.. this sucks for someone daytrading like I am

1) The rich investors knew the crypto market was going to plunge just before the SEC meeting.
2) They sold off their stocks (down 9% or so since Jan 22) anticipating the crypto plunge
3) They now have funds available in their accounts to play the crypto market.
4) Crypto market will go to astronomical levels it has never seen before, like 100k+ for BTC.
5) Media will talk about it nonstop, and ignorant masses (like I was a month ago) will invest buying at market price
6) This will become the new bubble.  Huge one.
7) The intelligent advantaged seasoned rich traders sell off and play/milk the market daytrading (with assistance of bots & computers)
bubble pops
9) Huge transfer of wealth, yet again from the ignorant lower class to richest people.  Just like the tech bubble, housing bubble -- now the crypto bubble.

Just a thought anyways

I did all the day trading on binance the past couple days.. perhaps over 100 trades total.  I am up like $40..  HOwever cointracking.info cap gains report says I am up more than three times that.   Thing is it has all my blnance alt coin balances correct.   So I know it all properly import.  I am also careful with bookkeeping the transfers in and out.

Any ideas what this is about? Driving me crazy.  

Does it have something to do with the constant price fluctuations of what I am trading?  i.e. both currencies are highly volatile.

Am I getting cheated?

Should I be using a program that uses the daily average value of etherium?  Been day trading on the Etherium market on Binacne for past couple days, all days.. agian up $40 but cointracking.info says I am up many times that sigh.

They didnt' payout yesterday . they did today.. but they raised the minimum Coinbase transfer from 0.002 to 0.003 .. suckers..  I am at like .00297.  sigh.

There was no payout today in Nicehash.  Anyone else have that problem?

I was excited to get this 1200W platinum EVGA power supply because it can power six vga cards -- currently using hx1200i which only powers five.

But I was very disappointed that it came with 4 sata cables and only 2 molex cables.  4 ports on the power supply are labeled "sata".  Is it possible to get some more "molex" cables and plug into the sata connections on the power supply?  Are the sata connections on the power supply rated the same as the molex connections as far as max wattage?

Right now I am using one molex cable to power two usb pcie risers. The other molex I can only power 1 because the cable isn't long enough.  For the other two cards I used CPU2 cable with a graphics card pci splitter.. powering the explomos usb risers with the pcie 6 pin (they accept that, molex or sata).  Now I have no idea how I am going to power the 6th video card riser when I get it.  Whole reason I got this power supply was to power six video cards.

Should I get a 3-4 way splitter off the CPU line?   one cpu cable to power three usb risers?  Or should I risk using sata cables for the last card?  Stinks they have so many sata ports/cables.

What's the best safe/vault type app for Android?  Something that requires a strong password to see the encrypted contents within.

I'd like to store all my Account information in it.  Also using this same factory reset Android solely for cold/offline wallet(s) & google auth.  I keep it in Airplane mode all the time and turn off airplane mode briefly when needed, then immediately back on.

This would be the perfect place to store this "vault app" or "safe app".   As I only use the android phone with highly trusted wallet apps & google auth (currently).  I use this device for nothing else.

I would also need the ability to back up this vault.

I also it needs to have very good encryption with no backdoors for the company who designed the app nor any hackers.

Thanks

Which coin should I purchase on GDAX to affordably transfer the funds to Binance?   BTC and ETH fees are quite high right?  Does it make sense to trade the currency on GDAX for Litecoin then transfer the Litecoin to binance?

Is there any cool website that compares how much it would currently cost you to send various cryptocurrencies?   Like you type in the US dollar amount and it shows you currently how much the fees would be for each?

My Nicehash payouts past four days on rig with 5 x 1070 TI GPUs :

1/25 0.00173621 BTC
1/26 0.00171633 BTC
1/27 0.00153533 BTC
1/28 0.00145217 BTC

Does this make sense? Bitcoin payout has declined quite a bit the past couple days.

I tried downloading the trial version of Microsoft Office 365 for the Mac and was really displeased with the performance and lack of functionality compared to the WIndows version.. e.g. the Mac Version does not have Data Query from Other Source.. e.g. to get the JSON data from coinmarketcap v1 ticker.

Is there a good way to get at this data in realtime in LibreOffice or Openoffice calc?  I suppose I could buy a used copy of Excel 2013 and run in a Virtual Machine on my mac.. would be like $20-40 for a used copy.

I need to update my outdated 100 mbps router as my internet speed is now 180 mbps.  I need to get a gigabit lan/wan/wifi router.

Any in particular you recommend?  Perhaps the least latency?  I'd like a router that has ability to install custom router firmware on it at a later date if I decide:  e.g. dd-wrt or tomato.

Thanks

I'm self employed and just wondering how I should report any gains from mining cryptocurrency.

I need an accounting method for treating the property received.  Do I put it in as inventory and use Schedule C?  Do I treat it as business property and report gains in 4797?  Or does it immediately become personal property and I report gains with schedule D / 8949?  I'm in Oklahoma.

I just started this self employment thing a couple weeks back.  The only thing I am doing is mining crypto and then selling it immediately or trading it for another crypto for short to long term investement.
I haven't chosen an accounting method for the property so it's flexible now.. again just started.

I am running Electrum (for Bitcoin wallet) along with Google Authenticator on a factory reset Android phone (which I no longer use as a phone).  It's the only two apps I have installed on it and I put it in Airplane mode right after using it.

This seems to be a pretty safe way to have a cold wallet right?  I'd think anyways.

I was wondering which is the best wallet for Litecoin on the Android, if there is one?

What do you all think about Burstcoin mining?  I could throw a couple 4TB HDD in my Nicehash rig and run both?
