For reset 2FA you need to login your account first, go to your account security and click on Reset Two Factor Authentication, then entre your new 2FA code for reset, remember to write down your QR code.
If you lost your phone you can use QR code to restore your 2FA, but if you also lost the QR code, then there are not much you can do, the only solution is to contact exchange support, and see if they can help to login your account. Sometime they refused to do that, that why is very important to write down the QR code and keep it in a safe place.

投资有很多方法的，我总结下我的方法吧。
先研究一个币，看这个币的用途，白皮书，网页，团队等等，如果真的看好一个币
就买些长期拥有。
还有一些币是短线的，自己先预测下这个能升多少，如果跌什么时候卖掉，自己
心目中有个上限和下限，然后到了就卖掉。
其实当韭菜也是一个交学费的过程，最好投资能力之内的，不要花掉所有资金，
这样不会损失太大，我个人提倡小的投资，小收益，慢慢累积经验，像一夜
暴富的投资方式，我认为风险太大。

I buy cryptocurrency part of reason is for investment, and also part reason for support a good project.
I think buy crypto is similar like buy stocks or shares, if I found good project and I believe they have good future, they might need a bit funding for start their project. If we look back some of the big company now, a lot of them started with a small project too.
I believe after 10 years some of the altcoins will be like bitcoin today.

To be honest I think some altcoins will survive and increase value after the bear market, but some of them will death and not able to return their price. I bought few of altcoins last year and most of them drop half of their value, I am still hopping they will return their value soon.

It definitely stress me. There was time I looked the price every hour and didn’t feel like to do anything else.
If I saw the price drop, then I started panicking and tried to sell the coins as fast as possible. If I saw the price return, then I started to regret my action.
After a while I found a solution to care less with price. I make a buy and sell orders now, in this way I don’t need to check the price all the time. I invest only small amount each time, so I don’t care if I lost or not.

这要看楼主对收益的要求，如果楼主想靠空投和羊毛代替收入，这个愿望应该很难实现。
很多空投和羊毛的确不是很靠谱，最终不会收到币，但还是有些会给币的。
如果楼主只是当做兴趣爱好，那有时间就搞吧。我还是对羊毛和空投很感兴趣，但是时间
有限，现在只能挑着撸了，我不想花钱投资买币，因为经验不够，投资了几次都是亏损收场，
所以只能玩空投和羊毛。除了空投和羊毛，如果有设备的话，也可以考虑挖币，我想收益会比撸羊毛应该高很多。

Yes, one time I didn’t receive my airdrop coin on kucoin exchange, so I tried to contact Kucoin exchange telegram group, someone in the telegram group pretended to be kucoin admin, and contacted me there and said would help me, then he DM me said that my airdrop wallet address need to be activated. If I send small amount ether to an address that he give, then the airdrop coin wallet will be activate and is able to receive my coins. Lucky I wasn’t trust him and I reported also him to kucoin exchange, he was immediately be removed.

For some business reason, some people need multiple accounts to promote their business. I think as long as the website owner accepted their requirements, then that is ok. It is pretty hard to track down multiple accounts without any personal information. For limit the options to create multiple accounts you can set mobile phones verification, or ask users to register with a credit card. You don't have to charge anything. You can just check that the card is valid.

I feel sorry for myself that I bought LTC when the price reached the highest point Lucky I didn’t bought too many and only one LTC. It was $300 and the price dropped mad since then. I heard BTC is the crypto gold and LTC is the crypto silver, that why I thought the price would rise like BTC. I am still hoping the price will recover one day.

楼主胆子大呀，不过现在应该是好时间投资吧，感觉已经差不多到底了。
如果有剩余的资金，现在是好机会投资。我还是喜欢不冒太多风险，
要投资也是小数目，可能这也是为什么有些人可以一夜暴富，有些人永远
没有这个机会，如果3W没有影响到生活，那是一个很好的投资。

If the market start pump the value, yes it might be possible to reach that price. It is really depend on what the market look like in the future, and how much supply too. The bull market can return next month, can also wait for few years to return. If the bitcoin popularity continues to grow next 2 years, then it might able to reach $100,000.

我就不明白为什么比特币的地位一直不能够被其他币取代，比特币转账很慢，
而且费用昂贵，现在出现很多新币，但没有一个还能够超越比特币。
而且比特币跌，几乎所有山寨币也会跟着跌，以前以为以太能够超越比特币，
但现在看来不是很可能了。

I got into crypto last year. I heard friends talking about bitcoin at first, and then I tried to search information about bitcoin. The first came up after Google searching was bitcontalk forum, after that I started my real crypto journey. There are discussion about bitcoin and altcoins here. We share our experience and information here, that was how I develop my interest in crypto.

可惜看不到楼主发的图，也很好奇如何通过交易量指标判断牛市来临。
不过熊市已经很长世间了，我总感觉严冬就要结束，牛市应该快来了，
这个只是我的感觉，没有任何依据 我认为只要能活过这次漫长
熊市的币，都会在牛市里享受丰收的果实。

I am still confident with crystocurrency and I don’t think it will be ending in this year or next 10 years. I think we are just at very beginning. It is a bit similar to stock market, so there would be a low and high point. We need to be patience and also invest with caution. I think right now is bear market, that why everything drop.

I don’t use Electrum Wallet, so I can’t give you instructions myself.
I find this old post in bitcointalk forum that it is similar question with yours, might be in the replied post you can find a good solution. Here is the link. https://bitcointalk.org/index.php?topic=2315182.0
I hope this could help you.

DarPayCoin is already listed crypto-bridge and coin market cap. Crypto-bridge is one of my favourite exchanges. This exchange is easy to use and has also good reputation. I joined DarPay discord few weeks ago, It provided different languages channels. If you have any question, you can simply ask in your own language. I believe DarPay will have a bright future.

Yes, 2017 was the best year so far for bitcoin. We don’t know the future. I think the glory for cryptocurrency will come in the next few years. I believe we are not reaching the highest point, we are not even half way there, there are still long way to go, and the future is bright for cryptocurrency. We need to hold our nerve and pass the worst time and it will get better very soon.

现在熊市的确不容易过呀，不过现在放弃真的很可惜，搞了那么久，都变成信念了。就连空投现在也不容易呀，我前几天推特账号被封，
而且是突然被封掉，没有任何警告，我就一个账号，而且用了很久，最主要是没有任何警告，现在一下不小心，就到处被封，真的是步步惊心呀。

You can check announcement (altcoins) session here. Bicontalk talk Forum is a popular place for alt coins to public their news. I found most the new coins here. You need to come here regular to check the information, sometime people like to discussion about new project and coins, you might able get earlier information before the coins are listed on to exchanges.
