I saw some Neo wallets, but I have a question about one of them. is http://neowallet.cn/ supports  nep-5 tokens? if No, please introduce some wallet that support  nep-5 tokens.

the market is bloody now, holding on exchanges has very risky, another side we need to hold fiat on wallets until market reach it's dip, so what is your suggestion for holding fiat outside of exchanges? witch wallet is good for this conditions?

some month ago, IOTA's wallets have some bugs and so some people lost their assets, is this problem solved? what is your idea of the future od IOTA?

I calculate the main prices of ETH and also BTC price regarding the mining process and costs. miners are the main people that affect the price of BTC and ETH. if the prices of coins will below the mining costs, the mining will not affordable. in general, if we consider the average prices of mining in all of the world, we conclude that the lowest prices of BTC is about 6000 to 7000$. and this amount for ETH is about 400$. so if ETH decreases more than 400$, the mining of ETH will not affordable and miners will migrate to other alts. so this migration will cause stopping the mining of BTC and ETH and also will cause the price of the transaction. in long-term, this causes the raising of the price for ETH and BTC.

I decide to explain XRM mining for you, so I wrote this guide. this topic will be updated in 2 or 3 days, because; I will spend more time to describe XRM mining completely.

Monero (XRM) is a digital currency based on the CryptoNote algorithm based on Ring Signatures. The Ring Digest allows Monero to create significant privacy when doing a transaction.
Monero uses Proof of Work to produce a new Quinn. Monero can be extracted using the processing power of GPUs and CPUs. There are currently no specific ASICs for Monero.
Monero mining can be done with home systems, but you should not expect to be profitable. So for Monero's extraction, you need to use relatively powerful hardware and systems.

These days, using graphics cards is a better way than the processor. In the process of extraction with the graphics card, the speed is increased and costs are greatly reduced.

In general, Monro's cost-effective extraction process is as follows:

1- Providing a powerful hardware system or extraction rack
2. Create Monero wallets to extract extracted Monero
3. Start extraction by running the required software and joining the pool extraction
Gather hardware and install the operating system

Extracting is possible with home computer systems, but it is not at all cost-effective. Monero extraction is possible with CPU and GPU or graphic cards.

The miner's extraction with the CPU is almost outdated, and today miners are more likely to use graphics cards to extract Ethereum, Lightweight, and, of course, Monero. So, we've also provided graphics extraction training for you.

To extract Monero's cost-effective extraction, you should have a graphics card extractor. Rig means a pack of hardware. The graphics card is actually the same as a home-office case but with a high-end graphics card.

You can buy extracted pebbles in the ready form or collect and assemble parts yourself.

one simple rig is shown in below image



In general, a extraction sand includes the following parts:
1. Powerful graphics cards
The main part of the Rig extraction is its graphics card. You need a powerful graphics card to extract Monroe. AMD graphics are better than Nvidia graphics.

Amd Readon Rx series, is currently the best graphics card model for extraction. The RX580 and RX480 are good graphics cards for this model. You can use a variety of graphics cards, but you need to get some powerful graphics cards instead of buying a lot of low-end graphics cards. Also, note that all your graphics cards are branded. For example, choose either amd or all nvidia.
By searching for any graphics card on the Internet, you can get its hash, and then extract its approximate profit by importing it into the Cryptocompare site's calculator.

Note: The hash of any graphics card varies in different algorithms. Monroe is extracted from the CryptoNight algorithm, which is a subset of CryptoNote. For example, the RX580's graphics card has a hash of 600H / S in the Monroe's algorithm, and has an output power of about 23Mh / s in the etherium algorithm. Be careful not to make mistakes in calculating profits.

Also, by visiting the NiceHash site and the profitability-calculator section, you can get your approximate profit by selecting any hardware.

2. Chassis

The chassis is a means for mounting the pieces of sand on it. You can make a chassis ready or you can build it yourself. The chassis should be such that the parts, especially the graphics, do not screw in well on it and are not unbalanced.

3. Powerful power supply
Take this section very seriously to prevent damage. For home systems, a power supply of 300-500 watts is sufficient. But for some graphics cards, you need power or powerful power. For example, for six powerful graphics, a 1200W wakeup is required in the PlusGold version. Be sensitive to picking up pigeons when picking up pegs and consult expert staff.




.
4 RAM

Extraction does not require much RAM. A 4GB DDR3 RAM is enough. If you want to do more than extract from your system, you can get a 8GB RAM.
5- CPU

For extraction with graphics cards, the CPU is not very powerful. An average CPU is connected to your motherboard.
6. SSD drive

7. Cables needed
8. motherboard
9. Internet Adsl + Modem
Extracting to the Internet does not require too much, but it's important to be stable and uncertain. The best type of Internet to extract Adsl Internet is that, if you have a fixed telephone line, you can activate your Adsl service via private telecommunications or private companies. Internet speed is 2 to 4 megabytes for extraction.

Best Monroe Extraction Pools
Two MinerGate and SupportXRM extraction pools are currently the best and most used Monroe extraction pools. The first one has a bit more work, but its simple interface makes it easy to get started with a few extra clicks. The latter is less costly and more professional, but the connection method is a bit difficult for beginners.

Power consumed
The power consumption of the graphics cards is very high, so some of the extracted profits will be spent on electricity.

as you see, recently our forum, use merit system for ranking the user inside user activity. some users are glad for this new system of the ranking and some other no. but Although this merit system is not Pleasant for someone; but it is very necessary for our forum because the ecosystem of bitcointalk forum will some advantage for below reasons:
1-first of all moderation of a forum is very hard work, so when some users sent Successive without searching in the forum, the admin's job to separating all of the posts had been very difficult.
2- without merit system; the database volume increased form spam posts! this cause to reduce the speed of loading of the forum and also Cause to Increase resource consumption.
3- sometimes this spams post if growth most cause to database error (in some sites occurs).
4- searching process and finding useful links was been difficult for newbies.
so after launching these new systems, we see that:
1- forum loading speed is increased
2- Saving time for administrators for moderation of topics
3- resource consumption is optimized
4- newbie users could reach their questions in with consuming low time
5- the risk of site downing is decreasing and so on.
6- the useful posts and topics increasing



but I think; the crackdown on merits may lead to some problems:
1- some users will be Discourage from bitcointalk forum
2- If someone that he wrote a high quality and original post, did not catch merit, may be left the group
3- some people will work on account trading for taking profit.

so; I think; the Overall idea of merit system is so good, but it may be optimized for more development of forum.

what are you think? are you agree?

How does the merit system work?

witch one of BTC ETH NEO LTC or IOTA will the king of crypto? please describe with reason.

[1- idea:]

I read the proposal of biometrids ICO i write my investigtaion result in below (From my point of view)

1- idea: Facial recognition conflicts with Blockacin's goals (poor: 2.5 from 5)
blockchain is developed to protect of human data. but when some one try to use blockchain in biometrids, the risk of Privacy is decreased to minimum

2- team: : team has not efficiency CV. (poor: 2.5 from 5)
you can search the team member and their facebook and other social networks. you can see theire flower is in minimum.
3- poorly welcomed: (very poor: 1 of 5)

The project is very poorly welcomed. please check their Social networks follower telgram group and so. ..

4- Promotional Team: (very poor: 1 pf 5)
the promotial team try to attract some follower but they could not do it. (very poor)

5- realiblity:
I will say about this some times later.

6-Popularity: (very poor: 0.1 of 5)
if you check their rank in Popularity, you can see the status of that (very poor)

check and decide.
