Bitcoin's digital currency rose above $ 4,200 on Monday for the first time in nine years of trading history.
On the US-based Bitfinex market, Bitcoin hit a high of $ 4,233.0. The latest price was at $ 4,211.4, up $ 152.1 or 3.75%.
Bitcoin has more than quadrupled this year and has risen about 47% in August. The surge means that Bitcoin's total market share has now increased to about $ 69 million.
Bitcoin has rallied to a record high set in recent sessions amid optimism that a faster deal will speed up the spread of the crypto currency.
New software called Segregated Witness, or SegWit successfully adopted by blockchain that support Bitcoin last week. The launch of SegWit is seen as a milestone for Bitcoin.
The software was developed as a solution to the problem of crypto currency scaling, which led to a split or so-called 'hard fork' on August 1st when the blockchain supporting Bitcoin was split into two, creating Bitcoin Cash.
Bitcoin received an additional boost after Goldman Sachs said in a report last week that it is increasingly difficult for institutional investors to ignore the rise in crypto currency.
"Are you sure of the benefits of investing in the crypto currency (you know who you are), the real dollar is working here and guaranteeing to watch," Goldman said.
Elsewhere in crypto currency trading, Ethereum, Bitcoin's closest competitor in terms of market capitulation, rose 2.89% or $ 8.47 to $ 301.29.
Bitcoin Cash, the newly created Bitcoin branch, fell 1.85% at $ 302.0, while Ripple was up 2.18% at 17 cents.
Bitcoin Increases Again after "Hard Fork"
Bitcoin prices moved up on Wednesday, one day after the blockchain supported the breakup of the crypto currency into two in an event known as the 'hard fork', creating two virtual currency rivalries.
At the US-based Bitfinex exchange, Bitcoin was at $ 2,749.2, up $ 11.4 or 0.42% after expiring on Tuesday at $ 2,731.2.
Bitcoin cash, the latest version of Bitcoin, launched on Tuesday, created a new crypto currency.
Bitcoin Cash was developed as a gauge to increase the basic technology capacity of Bitcoin, blockchain, a shared online ledger that records all transactions.
A recent surge in Bitcoin's popularity, with prices reaching a record $ 3,000 in June, means blockchain has struggled to cope with a surge in transaction numbers.
Blockchain Bitcoin can only have one megabyte of data added every 10 minutes, limiting it to seven transactions per second.
Blockchain Bitcoin can be 8MB, whose supporters hope to increase the capacity to process transactions.
Bitcoin holders from before the split have access to the same amount of Bitcoin Cash for free.
Elsewhere in crypto currency trading, Ethereum, Bitcoin's closest competitor in terms of market cap, was last down 4.57% or $ 10.51 touched $ 219.05.
# Bitcoin & Ethereum Drove Higher, Recovering from Last Week's Weakening
Bitcoin and Ethereum prices halted a recent decline on Monday, bouncing back after suffering heavy losses over the weekend due to fears of crypto currency bubbles.
Bitcoin was at $ 2,081.10 at the US-based GDAX exchange operated by Coinbase at 15.30 GMT, up about 6.6% or $ 128.90.
The crypto currency fell by about 13% on Sunday from above $ 2,000 to the lowest level at $ 1,758.20, a level not seen since May 16, and investors remain vigilant to start big positions amid growing concerns about the future of the digital coin.
On August 1st, a proposed Bitcoin 148 upgrade is scheduled to be activated, and if the majority of developers fail to agree to the proposal, crypto can be broken down.
In that case, the GDAX Coinbase market said in a blog post on July 13 that the exchange "temporarily suspends deposit and withdrawal of bitcoin in GDAX and may also stop bitcoin trading."
Bitcoin prices have dropped nearly 30% since reaching an all-time high of $ 3,000 on June 11. Despite recent losses, bitcoin has still risen nearly 62% since the start of the year.
Meanwhile, Ethereum, Bitcoin's closest competitor in the market cap, rose 15.2% or $ 23.70 to $ 179.64 in early trading. Prices have fallen more than 20% on Sundays to $ 130.26, the lowest level for more than a month.
Ethereum posted its fourth weekly loss in a row last week amid concerns that the crypto currency is facing a correction period after surging to record highs.
Prices have fallen by almost 55% since peaking at an all-time high near $ 400 in mid-June but still rising around 1,8005 a year.
Other leading crypto currencies such as Litecoin, Ripple and Dash also bounced back from weekend losses of 15 to 25% to trade higher.
The crypto currency reached the market peak of about $ 116 billion in June and has since lost $ 38 billion, losing nearly 30% over the past month, meeting the technical definition of the bear market.
