In the last 30 days, bitcoin has risen over 33 percent.Negative bitcoin news The rally may seem perplexing given that there have been a number of setbacks for the cryptocurrency.These include: The U.S.Securities and Exchange Commission (SEC) deciding to reject a bitcoin exchange-traded fund (ETF) proposed by Cameron and Tyler Winklevoss.This is now under review however.An ETF would have given further credibility to bitcoin and helped more institutional investors get involved.A fierce debate over the future of bitcoin's structure.The full explanation can be read here.Issues with some exchanges, particularly Bitfinex, which cut off their access to the banking system meaning customers couldn't make withdrawals in fiat currency.So why the rally?At the same time, there have been some positive developments.Firstly, Japan legalized the cryptocurrency as a payment method recently and this has led to a greater amount of bitcoin being bought with yen, according to Aurelien Menant, founder and CEO of Gatecoin, a regulated blockchain assets exchange based in Hong Kong.

The second reason could be to do with a change in the code of another cryptocurrency called litecoin.What happened with litecoin and why does it matter to bitcoin?Last month, there was a change in the code behind the technology that underpins litecoin.It is known as Segregated Witness (SegWit) and it allows the speed of transactions using the cryptocurrency to increase.This has given hope that bitcoin could see a similar thing.Fork debate recap To understand the issue, it's key to look at how bitcoin transactions are processed.Transactions by users are gathered into "blocks" which is turned into a complex math solution.So-called miners, using high-powered computers work these solutions out to determine if the transaction is possible.Once other miners also check the puzzle is correct, the transactions are approved and the miners are rewarded in bitcoin.But there is a big backlog in transactions and the speed at which these are processed is slowing.That's because the rules of bitcoin only allow a certain amount of transactions through in one block.

In mid-March, the price of bitcoin saw a big drop because the community was afraid of a so-called "hard fork" which could have led to two blockchains forming, and therefore two separate cryptocurrencies.But the example of litecoin shows that a so-called "soft fork" can happen which would increase the block size for bitcoin without major disruption."That example of a successful soft fork in litecoin has made people start to think that we could get a successful SegWit implementation in bitcoin and that could increase capacity and move us to the next level," Daniel Masters, director at Global Advisors Bitcoin Investment Fund (GABI), told CNBC by phone.ethereum tutorial videoGABI is an investment fund that is listed on The International Stock Exchange on the Channel Islands.bitcoin sklepAnd what does this mean for price?bitcoin nz law

While bitcoin has seen a recent rally, previous peaks have seen sharp pullbacks in prices.Masters said the price rise has been "violent in the short-term" with bitcoin "fully valued for the moment".This could lead to a pullback to around $1,100.However, the long-term outlook remains strong."In the 8- to 14-month horizon, my forecast would be around $4,000," Masters told CNBC.Others also expect high prices.Gatecoin's Menant said prices should climb beyond $3,000 this year.ethereum ipo dateAbout a year ago I bought 30 Bitcoins, the online peer-to-peer crypto-currency, for about £3 each using a European website called Bitstamp.net.asic bitcoin hardware ukBitcoins appealed to my inner crypto-anarchist and I felt they had great potential.mine litecoins macUnlike real money, they are decentralised and transactions are free; no bank in the middle taking their slice and nothing central to fail.cày bitcoin

Anyway, I forgot about them, and nine months on, in March this year, I saw some news about how their price was sky rocketing.I was amazed to find that my £100 investment was now worth over £2,000.This got me interested.I dived back into the crypto-coin world and started to learn everything I could about them.I also read up on things like the exponential market average crossover trading system, an age-old technique used by stock brokers.Over the next couple of months, to my astonishment, I managed to double my money.litecoin gpu miner hardwareI decided to cash out at that point, by converting all my funds into Bitcoins on BTC-E and transferring them back to Bitstamp, partly because I didn't quite believe it all.bitcoin payout per hashBut sure enough the money arrived in my bank account a few days later.However, at heart I've always been a geek and what had really grabbed my interest by then was how new Bitcoins and Litecoins are created.

To find new ones you have to "mine" them, which involves a computer doing huge numbers of difficult computations.The catch is that the more people are mining them, the harder it becomes to find new ones, so that the supply is limited.This means that they effectively have built-in deflation.So, about four weeks ago I took my £4,000 profit, added another £11,000 from my savings and set about buying and building Bitcoin and Litecoin mining hardware in my spare time.For Bitcoins, I invested in pre-orders of new, specialised mining hardware called ASICs.For Litecoin mining rigs, I bought lots of Graphics cards and built computers out of them in plastic crates.I also regarded this as a home R&D project for my main business, Memset.We're a hosting/data centres company and I've been keen for us to experiment with GPU-based cloud computing so I was reassured that even if it came to nothing, I could likely find a use for what I learned.Along my journey I had discovered that there were virtual securities exchanges games where one could float a virtual stock or bond quoted in crypto-currencies, and this too intrigued me.

I decided I was going to need some help, so rounded up a few more techies, two of whom I'd met on the bitcoin forums and another two who are work colleagues.They all agreed to help me out in their spare time in exchange for shares in my planned virtual company.Next, while on a scuba holiday between dives, I made a business model and plan for our new company, "CipherMine".After crunching the numbers, my model was forecasting that with an extra £25,000 investment, we could be making £20,000-£30,000 per month profit from mining by the end of the year.It looked like we had a virtual business with potential.By this point, I had also come to believe that Litecoins had greater potential for growth than Bitcoins, so I eschewed the Bitcoin exchanges and instead submitted CipherMine for flotation on Litecoin Global.We made our initial public offering on Monday last week.I think I probably got the IPO price a bit wrong since the 20,000 shares I listed sold out in a matter of hours.We raised a total of 15,667 Litecoins in exchange for 20% of CipherMine's shares; about £27,700 at current prices.

We are in the process of investing that money into more mining hardware, but in the meantime, our share price has continued to rise.As I write this, under a week later, the shares are being actively traded at about 1.6 Litecoins each; double the IPO value.CipherMine's market capitalisation currently stands at roughly 150,000 Litecoins, or about £250,000, of which 64% was mine at IPO.Again, partly to proverbially pinch myself and make sure it was real, I have sold a little over 2% of my holdings from which I've made about £3,000.CipherMine still owes me quite a bit, but if all goes to plan, my original costs should have been covered by the dividends on my shares come October.I still don't quite believe it and there is a very real possibility that all the value could vanish in a puff of logic.However, I started this as a hobby and in many ways it still is.I've learned a lot and had fun along the way, so if that's all it comes to, I'll be content.I cannot help but be quietly optimistic though.
