Hi~ dears,

I just hear that users actually don't want Merkle tree for their transaction as proof, is it because that has privacy issues or what? Quiet confused by this. 

如题，想找他们团队中的某一人，Twitter都行！ 跪求！

Anyone knows what happen to Bitfinex OTC? I cannot find it anymore. 

bitfinex不是有OTC吗 现在咋没了？

小额用户去哪里买比特币

推荐使用：CoinCola
官方网址：www.coincola.com
推荐理由：买卖无手续费，适合小额用户

首先咱们先看一看各个比特币交易平台的注册难易程度

比特币交易平台的注册难易程度
平台         电话号码注册           视频认证    邮箱注册     身份证认证   是否需要翻墙
OKcoin       √                      √                              √   
火币               √                      √                              √   
比特币中国       √                      √                              √   
CoinCola       √            
 
大家可以看到目前注册难度上来说：
★★★★★：中心化的交易所，需要实名制和身份认证
★：CoinCola目前任何国家的手机号码只要选择国家码和填写电话号码、设置密码就可以注册了。

然后咱们再看比特币交易平台的收费：

交易所收费细则
平台               交易费               矿工确认费                  法币提币费（RMB）
                                        （提币费BTC/笔）   
OKcoin        0.2%                  0.002                                  0
火币                0.2%                  0.0014                      0.4%
云币网        0.05%                  0.002                              0.1%
比特币中国        0.2%                  0.0002                      0.38%

OTC平台收费细则
平台               交易费              矿工确认费                      充币费                  广告费
                                      （提币费BTC/笔）   
CoinCola             0              0.0009                            0              0.3% - 0.7%

什么是矿工确认费：
比特币矿工负责确认所有的比特币交易，但他们不是无偿地做这项工作，比特币使用者需要向他们支付极少量的比特币以便让他们继续确认。这就是为什么我们每次在比特币网络中转账都会有微小成本的原因，这个成本就是矿工确认费，同时也就是各平台提币需要收费的原因。

什么是广告费：
广告费是OTC平台的东西，OTC平台就是像淘宝一样，有很多人开店，开的店有个展示页面，在OTC平台里一样，不过都叫做发布广告，可以发布购买广告和出售广告，分别用于收币和卖币，就相当于是开店，所以每次店铺有成交，平台就会抽取一定的手续费，这部分费用就是广告费，目前收取每笔交易额的0.7%，交易量大的卖家可以跟平台谈金牌卖家计划，可以把手续费降低到0.3%。

提币速度：

综上所述：
考虑到大家只是小额买卖比特币，所以：
1. 买卖如果收费的话成本就比较高
2. 交易所都需要实名制进入门槛比较高
3. 提币速度也比较慢，好几次在OKcoin买的币今天买的明天还没到。

所以建议大家买小额要快速拿到手的话，去CoinCola吧（www.coincola.com）

自从上次从两万多跌落到一万三，比特币最近又要突破2万人民币大关了，但是很多人都不知道怎么购买比特币，特别是很多人因为无法办理银行卡、无法使用银行卡支付等需要用到微信支付，我上次在一个Party上了解到很多外国友人只能使用微信，因为他们的工资都是微信支付到账户里的，所以我想很多人需要用微信购买比特币吧。由于本人各种机缘巧合，了解到一些可以购买比特币的网站，下面给大家介绍一下怎么用微信购买比特币


www.coincola.com


在地址栏里输入www.coincola.com（CoinCola），然后用手机号码注册一个账户，然后在买币列表里找可以用微信支付的卖家广告，点击购买。

担保交易，也是下单之后就冻结卖家的比特币，不过这个网站下单之前下单之后都可以联系卖家，总之下单之后按照卖家说的方式付款，然后等待放币。卖家释放之后就可以在钱包里看到自己刚刚买到的比特币了。


注册难易程度：注册免费，买、卖不收费，不需要翻墙。

交易手续费：发布广告收广告主每笔交易总额0.7%

转出转入是否收费：转出收费（好像目前是每笔0.0009BTC），转入目前不收费

分销体系：也可以分享链接，好友通过分享链接注册并交易，有交易手续费（目前我测试出来应该是15%左右），但是可以永久成为你的分销会员，这一点来看还是不错的。

有哪些版本：有安卓app，苹果app，还有网页版本，都有中文和英文。

我在网上搜了搜，13年开始就有了一些帖子，但当时不是做比特币交易，而是比特币支付，整个app的体验上还算不错，说明确实是花了很多功夫想要做好。客服方面，处理问题蛮及时，但是目前用户数似乎不是很多，估计也是在聚集人气的阶段。

With the rising number of  foreigners live and do business in China, they got RMB and want to buy Bitcoin, but those exchanges in China can trade only after ID verification, and only with Chinese ID, so how to buy Bitcoin becomes a big problem of foreigners live in China. There are two different way to buy Bitcoin in China, now we are going to talk about them.

1. Offline trading
You need to find someone who have Bitcoin, and they are willing to sell it to you, and this will be difficult especially for new Bitcoiners. And we all know there are some other problems with offline trading, if buyer pay first, then seller send Bitcoin, the problem will be buyer paid and seller do not send Bitcoin. If seller send Bitcoin first, the problem will be what if the buyer would not pay the money? So we will solve this problem later.

2. On line P2P trading platform
In order to solve problems as follows,
(1) Got money to buy Bitcoin but cannot find those who sell Bitcoin
(2) Got Bitcoin to sell but cannot find those who what to buy
Some company figure it out that they can develop a platform, just like Ebay, those who have Bitcoin to sell can create an ads on the platform that will display it so that those who want buy Bitcoin can find them and contact them directly through the platform. Then, Problem solved.

But still buyers and seller still have problems, they cannot trust each other:
(1) What if I paid but they would not send me Bitcoin
(2) What if I send Bitcoin but they would not pay
The platform figure it out with a new solution, Escrow payment, if the a buyer order some Bitcoin, lets say 0.5 BTC, then the 0.5 BTC from the seller will be held by the platform like trustee.
If the buyer paid, the seller can click a button that can release the 0.5 BTC to the buyer, but if the buyer do not pay, seller can dispute on the platform, the platform will sentence the 0.5 BTC to the rightful owner.
If the buyer paid and the seller do not release Bitcoin to seller, buyer can dispute too. The platform will sentence the 0.5 BTC to the buyer.

Here is the platform, named CoinCola, web: https://www.coincola.com, which is located in HongKong, here are things you may want to know about it,
1. You can buy Bitcoin as much as you want and without ID verification.
2. It delivers Android Apps IOS Apps and website, so you can buy and seller whenever and wherever you are.
3. You can register without VPN, since you live in China and with the regulation of VPN.
4. Register, buy and sell are totally free, advertisement will cost the advertiser 0.7% of the total trading amount.
5. Overseas seller will get supportive policy which will cut down your fee of advertisements to 0.3%.
6. New user can buy Bitcoin at a very good rate, normally will be RMB 500–800 Yuan lower than the market price.

I use it when I in mainland China, it is pretty good, and I hope it can help.
