I see this question alot, and the usual trolling/sh1tposting and unhelpful replies that follow.

In good faith i will share some tips and tricks on what coins to mine, with a focus on finding newer coins with high volume returns.
So without further ado, lets gets down to the brass tacks.

Check: https://coinmarketcap.com/new/
Only coins with 100k daily market volume get listed so, so it gives you a idea of coins that have at least some action.
Tip: Coins with a asterisk are not mining coins.

Nicehash has a profitability calculator that will show the best current algorithms to mine if you prefer to go for highest gains possible only and its respective coins.
This is so volatile i prefer not to bother with it, but i mine alot of coins i intend to hodl, shelf and forget about till i realize they either never made it, or made me a ton

Alot of these coins you wont hear about anywhere or even know they exist, and they are nicely placed all in one great spot.
Be sure to donate something, alot of time and research goes into this page.

Check: CoinDesk and other well known crypto news sources. Coins and ICO's getting mentions in the industry news have a leg up.

Alot of information can be found here. news, exchanges, ICO listings etc etc.

Check Twitter: Twitter has alot of "crypto OG's" such as WolfReloaded, WhalePanda, IAmNomad, PanamaCrypto etc etc. Follow the industry leaders.
I got a big break through in XMR thanks to one of these people.

Follow exchange twitters and research the coins they announce they will list.

Check: https://bitcointalk.org/index.php?board=159.0
I typically sort by replies and review the projects with the most, looking for new minable coins. I spend alot of time lurking in here.

Spend at least a few hours or researching these things and more to find great coins to mine.
There is no easy answer and everyone has their own reasoning, opinions and beliefs for "what is the best to mine".
It takes time, research and hard work to be at the top of the game in mining or trading.
If you want easy i suggest getting you get a forex broker. or paying a fee to one of the many private trading groups.
A professional will do all this for you. But it wont be cheap.  https://www.bitcoinmasons.com/ is a great place, one of many.

I am trying to figure out who people are able to mine with both Nvidia and AMD on the same rig.

So far i have uninstalled all AMD and Nvidia drivers with DDU after trying and failing to get claymore zcash miner to read the AMD GPU, and this is the message i was getting:

"No AMD OPENCLGPUs found, exit"

Even though the RX 580 card were shown in the device manager.

The 1080Ti were shown as well in the device manager. I did not try mining on this card.

There seems to be a driver conflict that i am overlooking or not setting up right.

So how can i and future miners get this to work so that both AMD/Nvidia cards are able to mine? Not having alot of luck with what google is showing me.

Some years ago there was some rumors that one could use ASICS to mine X11 algo that were proven true(allegedly).
Now i understand there are X11 specific unites for sale now, but with a high price tag.
How might one be able to use a basic ASIC to mine X11 say a block eruptor or older cheaper
units such as a the Antminer S5?

Are there any reputable exchanges that will payout USD from sell of BTC to paypal?

This issue has been resolved

With the monster acis units on the horizon of a full scale assault on btc soon(when they start mass shipping) and the ensuing skyrocketed difficulty level,

which coin will be the next big thing to mine?

Me personally i think the PPcoin since it too can be mined with a acis machine and would be perfect for us light wieghts who wont be able to compete with the tera hash/s powerhouses.
