Bitcoin is a great project, his various advantages as everyone knows, But he has two disadvantages:1，The transaction confirmation for long time, more and more long time.
2，Mining spend a huge amount of power energy, more and more.
According from Baidu's information (
http://www.baidu.com/index.php? Wd=%E6%AF%94%E7%89%B9%E5%B8%81%20%E7%94%B5%E8%83%BD),
Bitcoin miners every day used 1000000 degree power -- yes, is 1000000 degrees, the total cost of $150000, to mining bitcoins.
1 degrees of electricity =1000 kilowatts / hourThese two disadvantages will continue into 2140, the more than 120 years, how much power energy used, who to calculate?The root cause of the two problems, only one: the more and more difficult mining algorithm (the current difficulty is 4250217919.8695354, the minimum is 0.00024414). Why?
1，At present the currency transactions are dependent on the block above the miners, dig one block is one confirmation. Due to mining is more and more difficulty,
More and dug into the block probability is low, to confirm the time more and more long.
2，Due to mining is more and more difficulty, dig to block more and more low, mining the increasingly long time, open the computer is the need of energy consumption, especially the ASIC machine, consumption of energy is more and more high.
The core value of the coin, is transaction with no center,not mining.Now we know the problem, then we must have a way to solve it.
solution # 1, POS (proof of stake). All coins are premined, and send equally to each person. Then POS will have an other problem. Who is going to send those coins, and how we can keep this fair for everyone? If it handle by a man, the percentage of cheating will be high.
solution # 2, Use lowest mining difficulty, let CPU and GPU can easily dig the coin, but to prevent the ASIC machine, don't soon after digging all coin, to ensure fair competition. I accept this way, why?
1）Because of mining at the lowest difficulty, we can easier use CPU and GPU to mining and find block, it solve long confirms time.
2）Because of mining at the lowest difficulty, we can fast mining coin, it will save lots of power energy.
3）Every miner knows, the ASIC machine is very powerful, in the lowest difficulty will pretty much one block per second. If we don't put a limit, all coins will mined soon by ASIC machine.
How to prevent ASIC machine? We use time limit to control. Every two minutes, only one block will be accepted. And for all, mining will be not depending on the hash power, but a bit of your luck.
By the limit of block time, this will makes cpu and gpu mine more for each person, and being eco-friendly but keeping fair for everyone.
Hotcoin dev team is following this thought to research and develop into Hotcoin. We want to make sure your transaction COMFIRM FAST, ECO FRIENDLY, and FAIR FOR EVERYONE.
The second generation crypto coin, what is you need?
比特币是一个伟大的项目，他的各种优点众所周知，我就不说了。他有两个缺点：1，交易确认时间长，越来越长。
2，挖矿耗费巨量电能，越来越多。
根据百度提供的信息(
http://www.baidu.com/index.php?wd=%E6%AF%94%E7%89%B9%E5%B8%81%20%E7%94%B5%E8%83%BD)， 比特币矿工们每天使用100万度电能——对，是100万度电，合计耗费15万美元的电费，来挖掘比特币。
这两个缺点将持续到 2140 年，这一百二十多年里，要耗费多少电能，谁来计算一下？。。。造成这两个问题的根源，就一个：越挖越难的挖矿算法(当前难度 4250217919.86953545，最低难度 0.00024414)。为什么？
1，目前比特币的交易都是依附在挖矿的块上面，挖一个块算一个确认。由于挖矿难度越来越高，
挖到块的几率也越来越低，确认时间越来越长。
2，由于挖矿难度越来越高，挖到块的几率越来越低，挖矿的时间越来越长，电脑开着是需要消耗电能的，特别是矿机的加入，电能耗费越来越高。
加密货币的核心价值不在于挖矿，而是交易去中心化。知道了问题的根源，我们就有解决它的办法。
方法1，全部预挖，然后平均分配给每个人。这个方法产生新问题，谁来分配？怎么公平分配？人为操作，作弊的几率高。
方法2，最低挖矿难度，让cpu和显卡都能很容易挖到币，但要防止矿机，不要很快挖完，以保证公平竞争。我个人接受这个方法，为什么？
1)，因为挖矿难度最低，很容易挖矿，cpu,gpu都可以挖到，解决交易确认时间长问题。
2)，因为挖矿难度最低，挖到币的几率大大提高，也就大大降低了电能损耗。
3)，众所周知，矿机的算力很强，在难度最低的情况下，几乎一秒钟挖一个块，如果不加以限制，所有币都会被矿机挖走。
怎么防止矿机，保证公平竞争？我们采用时间限制法。每两分钟，全网只接受一个块，挖矿不再完全倚重算力大小，也许还需要点运气。
通过算法限制矿机，让cpu和显卡获得挖到币的机会，大大降低电能损耗，提高公平竞争力。
豪特币-Hotcoin，完全按照这个思路开发，交易快速确认，节能环保，公平竞争。
第二代加密货币，你觉得还需要什么？
