It would be hard to predict what will happen if a global crisis came again there are possibilities that all crypto market will drop a lot that can result of panic selling, but I think some exchange will stop to exchange any cryptocurrency because they are afraid to become exhausted until the global crisis stop.

However, since bitcoin is unpredictable we don't know what would happen in bitcoin if the global crisis came, but I think it's impossible for now to meet the global crisis again these following years.

I think gdax didn't allowed to use bots or coinbase but only few altocoins are available to exchange from bitcoin to electrum or bitcoin cash or litecoin. Other exchanges are allowed to use bot trading.

Why you need a exchange site that don't allow bot tradings?
Local exchanges that I think would the best option.

There are many traders are looking for exchanges from crypto to the US, which is great, but the problem they don't have an option to withdraw it instead you will still exchange it into cryptocurrency before you can allow withdrawing them.

I hope that they can also add the withdrawal option for USD so that we can easily exchange bitcoin or altcoin to USD and withdraw them once we need it. The good thing is there's no volatility if you exchange your coins into USD.

Anyway, thanks for posting this news here because if I didn't know this news I will never trade on Bittrex.

It looks like a control board is damaged or the cable is not fix properly, try to replace the cable then check it again.
Also, do a hard reset 3 times sometimes could fix the issue after upgrading it to new firmware.

And I think it's better if you put the kernel log here or copy paste it in pastebin so that we can find the problem of your miner.

You can follow the troubleshooting guide here

That is why if you don't believe on bitcoin your throwing the opportunity to make a profit.

There are many people don't believe on bitcoin those who experience of being scam in bitcoin that is why they are keep mumbling that bitcoin is not a real investment or they spreading FUD's to keep bitcoin down and there are traders wanted to push the bitcoin down so that they can buy a cheap price of bitcoin.

So for those who newbies please research first before you invest in bitcoin so that you will not regret in the future, people who believe in bitcoin are those who are lucky.

Gas price safe low sometimes not work based on what I experienced before since you are using the metamask wallet I suggest you don't edit the given gas limit and only edit the gwei with recommended or standard gwei price from https://ethgasstation.info/

Better explanation about gas you can read it here https://myetherwallet.github.io/knowledge-base/gas/what-is-gas-ethereum.html

and you can check here https://www.myetherwallet.com/helpers.html what is Gwei in ethereum,.

Every time you make a transaction you must always check the ethgasstation.info so that you know if what are recommended gwei prices.

There are many people talking about bitcoin dying and bitcoin is already experienced how times it dies, but until now bitcoin still alive and the price is different price compared to past years ago and bitcoin believers are keep growing using bitcoin.

Look at the coinmarketcap you see the volume in 24 hours still high and there are many people are using bitcoin not only in trading purposes and I think in some local businesses and online business to accept bitcoin as payment.

However, there are people still don't know what is bitcoin here in my country so if bitcoin can advertise again on TV or in social media (like facebook or google) maybe there is a chance that bitcoin price will jump high again because it might be a reason of a large price drop of bitcoin in the past few months and people are thinking that bitcoin will die.

Anyway, there's another chance that bitcoin will be trending again in social media since there are still people who don't know about bitcoin there is a chance that bitcoin can be trending again that could jump the price high and bitcoin will never die.

It looks like a testnet script hash this is use only for testing purposes.
Take a look at this wiki https://en.bitcoin.it/wiki/List_of_address_prefixes
I think you can try to disable it by typing this command.


Or edit and add testnet=0 in your .conf file.

Coinbase is only best to use as a wallet not good for trading I think it is better to transfer your bitcoin from coinbase to other exchanges like binance, you can trade bitcoin in other altcoins you like and hold it for a long time, but make sure to always monitor the movement of the price and if you see the price is gaining above 10% of your investment you can exchange it and save your profit.

Another exchange site is cryptopia.co.nz and I suggest that you invest small amount so that you won't lose a large amount if you do wrong.

Not only this may be the reasons of buying bitcoin I think there are other complaints like they buy bitcoins to use it in some website that only accept bitcoin as payment.

Bitcoin is unpredictable and any time the price can be fall or jump, bitcoin is like a roller coaster, but the difference of bitcoin the price every year is different compared last year.

FUD's could push other holders to sell, but I think for now true believers of bitcoin could hold their bitcoins tightly unlike newbies or newcomers who enter the field of Cryptocurrency are those people who sell their bitcoin with or without gaining profit.

What I see right now about the price of bitcoin it looks like there is a big group who can manipulate the price of bitcoin because sometimes there's a massive price jump or large dump.

I think the only way that you can get the latest bounty campaigns is to check the altcoin announcement section from time to time if you found a thread, which is low post and views it means that the thread is new and check the thread if they also announce the bounty campaigns because there are some new projects and ICO's not giving any airdrops or bounties, so you must checking the whole announcement thread and try to ask them about bounties, this is just what I am doing before that I wanted to earn some airdrops and tokens.

However, most of the exchange sites they don't allow to give the funds out without verification so I think the only thing that he can do right now is to verify his account with government ID or anything that Poloniex required so that they can fully out the funds from the exchange site without a problem.

I think this is the reason why Poloniex is collecting a personal data and verification it is because of GDPR and it's already started last May 25, 2018 I received this on email and also, I read this article from here Yes, The GDPR Will Affect Your U.S.-Based Business

And also other countries are affected by this new rules and if they don't follow the new policy they should pay the fines up to $2 million.

So this is I think the reasons why they are now asking for personal data and verification.

You move it again in the wrong section and I think you don't know where to move it.

Anyway, I suggest you to move this here https://bitcointalk.org/index.php?board=160.0 in altcoin mining section or make a new thread there and delete this thread.

It looks like same as coins.ph from Philippines you can pay the electric bill and other local bills, but the problem it needs a KYC first to be able to have an account in coins.ph and you must live in Philippines.

As of now the only way that I could see would be a good alternative for this I think physical bitcoin debit card without a KYC for privacy purposes since GDPR (General Data Protection Regulation) release a new policy this is a great alternative cryptocurrency debit card with online apps that you can pay online with bitcoin or altcoin.

However, about your example, it is just like a trading, but he is paying the bill to receive the altcoin or bitcoin. I think it is better to keep all process instant than waiting for other people to pay the bill of Mister X.

Customers are always looking for an instant so this is not a good idea.

I think if you want to pay less fee for every bitcoin transaction you must use a wallet, which is segwit support because it gives you less miners fee than using unsupported segwit wallet or legacy wallet.

If you use a wallet with segwit addresses every time you send a bitcoin to other bitcoin address they charge you a small amount of fee compared to non-segwit addresses.

I suggest that you use electrum wallet instead because it supports a segwit addresses and you can adjust the miner's fee from high to low.

The other wallet that I use is coinomi which supports segwit addresses for bitcoin and the good thing they also support altcoins and ERC20 token.

Awesome website it gives me earnings estimation in any different miners.

Well, these days there are many investors and miners come up and keep expanding that affects the mining difficulty that could result of low profitability and honestly, bitcoin is well known and always in the news content that is why there are new people coming and investing into mining.

I bookmarked the website for future references.

Maybe they're busy and honestly $5500 is a large amount of money.

Well bitmain is not scam maybe they are busy to assist all their customers and all their hardware is in demand this year.

Just keep contacting them and send a ticket about your issue so that they are aware about you.

Honestly, bitmain these days were getting worse because the quality of their miners compared before is different.

My miner temp is kept reaching 80c+ on the day, but every night its keep cooling down to 80c below with AC 12,000 BTU and 1.5HP, the old antminer still kicking compared to new one.

Since, you vented your miner outside and keep your miners temps down, unlike mine that I put my miner near to our windows just to keep the heat out because if the heat stays inside in your room the air inside of my room is mixed-up.

Anyway, maybe your other 2 miners why the temp is high it's because of big dust on the fan or the exhaust fan couldn't blow air properly, try to clean the fan and fix the vented to blow the air outside.

It's impossible that the price of bitcoin will drop back to $2k or $1k the price of bitcoin is depends on demand and supply don't compare the bitcoin price in the past because the demand is low and the supply is high that is why the price of bitcoin is low compared to the current price.

I think this is just another part of FUD's they wanted to let people panic in selling bitcoin so that these FUDs could buy a cheap price of bitcoin and holding it for a long time and get benefits of holding it. These people are greedy and this is just like other people before wanted to push other people to sell and regret soon so if you are holder I suggest that you control your feeling and hold your bitcoin tightly.
