I'd really charge small payment accepting BTC/tokens for the ICO listing just started this previous month but Fastinvest is an exception here tho since I'm part of it's campaign well it's obvious that I just want to support the project in my very own way.

Probably

I have seen so many issues about this site lately, you can even search "cloudbet scam" on google before you used that site so you will find all reviews especially on this forum. You can go here

There are lots of scam accusations same as you did, but above post are only few of them.

I get here to announce that Forty Seven Bank ICO project is now listed on our very BL4nkcode ICO List. You can share, like and retweet those social media posts for your support to the project

Base on what I search on google.com I found this site www.bitcoin.de, which is based in Germany, so far I found  nothing bad review/s about this exchange. And you can even ask this on your local boards on this forum if you're a local of Germany.

Instead of making and asking such thread why don't you use the search button it might be helped, Google.com is a big help also if you don't know .
Go here https://bitcointalk.org/index.php?topic=615953.0 and look if there is an open slot for your rank.
Well, even if there is, I bet no one will accept you if you continue this kind of posts.

Mostly bitcoin wallets not exchange have this feature, I only know electrum desktop wallet, exodus and mycelium for mobile, while blockchain wallet can signed message only using its imported address and not the watched only address. If you're using another wallet you can export the private key of the address you want to have a signed message then import it to the wallet I mentioned except for exodus since it doesnt have an import feature..

Find the tab where you can signed message, it has 3 textbox on it, for the address you want to have a signed message, your message, and the signature which will be generated after you clicked the sign button..

So many aspects that can affect bitcoin transaction fees;

First is the numbers of inputs/and or outputs of your transaction, so
Avoid having too many dust/microtransactions   
And even wallet you used might be one of the reasons for having huge fees without your notice when you make a transaction, so avoid this kind of wallets sometimes blockchain.info wallet users experienced since this

I have a big guess that the main problem is your internet connection, I didn't encounter this kind of error eversince. For more convenience using blockchain.info wallet, I will suggest that use their mobile app so it will need a small amount of data and can load the app easily including the sending option.

There so many crypto exchanges that are user-friendly base on what they look, but unfortunately most of them are not customer friendly, customer supports responds too long and will take weeks and even months. If you want to buy bitcoin in Saudi arabia I'll suggest that go on localbitcoins here https://localbitcoins.com/country/SA, always choose a trusted seller that has many activities and positive reviews.    

Exodus desktop is one of a kind wallet I liked, the theme and the whole design of the wallet is too nice. But you can trust them also, on exodus you can fully control the wallet and your funds since you can access the private keys of the wallet. But the only thing I want them to implement is the dynamic fees or the feature where its user can manually put the fees. Because the current version doesn't have this feature, the software itself put the fees when you want to make a transaction base on the recommended fee. But overall the wallet is good IMO

So how can you get a payment around $70 from 5 days when on their site is clearly stated that an ordinary PC can get $25, gaming $50 per month, now how can you get around $70 within just 5 days?
And seriously I will not trust installing any unknown miner to my computer just for this.

Caution: This account is temporarily restricted. Lol
Anyway a nice bot that tweets some specific altcoins out there but its useless since the account dont have some decent followers. If you can implement this bot to a telegram bot then it might something better.

Its not the fault of the miners, they don't stole your btc and they have nothing to do with that, wallets are design to compute the recommended fee so it can be confirm faster base on the current situation of the network and based on your inputs/output of your previous transaction. 65643 bytes is pretty huge size you might have so many small amount of transactions(inputs/outputs) before thats why you experiencing this.

24-word seed phrase is only use to recover your funds if and only if your ledger nano s lost and you forget the pin as you already said.

And If you dont use your ledger for 5 years it might be impossible that you still remember the pin of the ledger without using it in a long time, so of course the 24 word will be use to recover it.

But if you still remember the pin then you can send it to some address that you own the private keys or seed then you can reset the device and get the 24 word seed and send back your funds to the address generated of your ledger.

Fast Invest ICO project is now listed on Bl4nkcode ICO List. You can view the listing below and if possible you can retweet the tweet and like the Instagram post.

Update: From now on I will use different addresses (from my HW ledger nano) for every trades related to BTC. Tho I'll still use the previous address which is this one 1A7eegrhDp91vvPn7yrhGj4VRAcJJuJEzn. And always ask a signed message with my personal wallet(on my profile) or the address mentioned here to avoid dealing with impersonators.

Added: Trade for ERC20 token which is 500000 token for P2PS Bounty campaigns, link https://bitcointalk.org/index.php?topic=2386388.0

Your browser might be the reason for this issue second your internet connection. You can try to;

Clear cache your browser, and try again to log in,
Use different browser,
Use the mobile application (Android/IOS) of blockchain.info which requires only your pin when you open the app,
And check your internet connection too.

And reply here if you still encounter that issue.

So you're running another paid transaction accelerator? Do you own a pool? and mind sharing that info since most users/accounts here provided with paid
accelerator but in reality they just use the free accelerators like you mentioned.

I confirm that I hold and escrowed the 500000 token payment for the P2PS twitter and telegram campaign.
