The data, you see on the forecast revenue don't reflect your real expected earnings, because you must deduct the fees. So you will not be able to withdraw until the contract will end. Hopefully they will pay then.
OK, to your questions. In my experience best results are on choosing two pools and to change them every three days.

Your problem with PAC brings me deja-vous in mind about my experiences with PAC last year with same issue. Fortunately I could sell them for doge (with loss) on cryptopia, but they shut down dogecoin market.
There is one market, where you can still sell your PAC for doge. But I have no experiences with this exchanger. Some still want to buy PAC, because there are pretty many buy orders.
Here you see all markets:

And here is the PAC/Doge tradesatoshi market

Maybe because we never get a chance for acceleration there?
I tried out several free accelerators. None of them worked out. I didn't try out OP's accelerator yet. But actually the fees are moderate and we can also use segwit addresses.
Yupp, it is not showing. Maybe you didn't copy the hash correctly. Put in sending or recieving address on search field in blockchain.info Or the sendings are still not provided.

In Coinomi limits are not shown as long you are within limits. But as you already stated. They defenitively have limits. And even if not, I don't see the point, why they should have limits as long as there are no fiat traded.

Yes, I did it just for fun and to get an insight view, how that works. It is very easy to create (cost one wave), but only recommended for seriuos projects. Just to create a coin wouldn't be enough for successful trades.

You are right. But there are many users around on MEW, who are not familiar with correctly handling the gains of forks or simply want to keep their funds on one wallet. For these cases the warning is senseful.
But your advice to move funds and simply gain free coins is better. 
To OP: Many thanks for sharing.

 I saw many arbitrage services and apps but this one is for me the most handy to get a quick overview on cryptocurrency prices. Fees and conditions can be researched and needn't be provided in your app in my opinion. Thank you very much for your nice arbitrage tool.
I bookedmarked your site and it will hopefully be continued a while.

You could launch interactive lessons for beginners about cryptocurrencies, blockchain, buying and selling cryptos, also trading and so on. You would probably have many visitors on your site. Maybe integrate some coins as bonus for each successfully completed lesson.

To claim "Transparency", "Honesty" and "Fairness" while pumping coins is a contradiction that everyone should see. In the traditional financial world we would talk about crime. In any case it is illegal and will handled by exchangers like that, if they catch you pumping coins.

Many newbies begin with cloudmining, because they simply don't know, where to buy cryptocurrencies as I experienced. They see ads on emails, websites and also contracts on a popular online auctions platform.
It is often more difficult for a noob to find an exchanger, where they can buy Bitcoin without need for a long and difficult verification process or to find a fair seller.
So for them it seems much easier to just buy a contract on cloudminer
Citizens of some countries like Austria are lucky to have Bitcoin ATM, so it is easy to buy Bitcoin.
Fortunately there are a few legit and trustable exchangers, which I can recommend them and also great sources here on bitcointalk for getting them intodruced into the basics of cryptocurrencies.

Payment recieved. Many thanks.

But abusing merit system with multiple accounts will be fast uncovered, because you see, who spent whom merits.

I sent you one merit point. Is it now in your main balance or at spendable merits?

No need to add a mobile app. Download Opera mobile and make a shortcut to homescreen. The text will be shown in adjustment to your screen, so that you can read without scrolling each line sideward. You can adjust the view an several mobile browsers.
You will see, that bitcointalk forum is one of the mobile friendliest sites.

Did you have a contract over 5 months? I have and my ROI from beginning up to now went significantly down. I even can't withdraw anymore, because I will not reach the 500$ withdraw minimum.

Isn't this almost the official price? Gunbot with only one exchanger costs 0.056 BTC, if it is baught with 10% discount, it is even much cheaper. Or did I get something wrong? Maybe you have some additional features?

OP's deposit issue seems to be solved, as we didn't see any post here anymore. So I think, it was just slow network (fees too low?). Even if Cryotopia would be overloaded, BTC generally should arrive, because deposits automatically processed.

GAS on Ethereum is called the transaction fee, that is paid with Ethereum or Bitcoin.
GAS on NEO is an own cryptocurrency (an asset of NEO)
I found a good explanation in this article:

You could devide your coins into a few parts. One part for longterm invest into wellknown coins like example for Bitcoin, Ethereum, Monero and Litecoin. Don't keep your funds in just one coin. Take the second but very little (maybe 1/10 of your whole funds) part for short/midterm trading. I could recommend you cryptopia. There are many infos and it is a good exchanger. .And you will learn much about crypto here:
https://bitcointalk.org/index.php?board=39.0
You could also try the faucet on eobot ( but don't invest)  You will have a good insight about cryptocurrencies with their interface.

No, cloudmining is not a good way to invest. Most cloudminers are scam, who don't pay out. Even if you would find a legit cloud miner, you would get your investment back in earliest one year. That is a long time, too long to get your investment back, before the service will shut down.
