As far as i know bitcoin has a high volatility given the fact that it is in demand in the market but i did not expect hat it is so high that it can really go from 1-100 and 100-0.
I want your insights about this volatility of bitcoin.

Bitcoin had a lackluster week, with dramatic drops midweek that made some question the hype cryptocurrencies had generated in the latter months of 2017. And then it started to recover, reminding us how erratic cryptocurrencies are. Reports that regulators may soon come to get tough on the market and evocations of the Great Depression made for a particularly tempestuous week in the already-chaotic world of cryptocurrencies. So what happened—and does it mean anything?

Here’s a look back at how the week unfolded

India has sent tax notices to tens of thousands of people dealing in cryptocurrency after a nationwide survey showed more than $3.5 billion worth of transactions have been conducted over a 17-month period, the income tax department said.

Tech-savvy young investors, real estate players and jewellers are among those invested in bitcoin and other virtual currencies, tax officials told Reuters after gathering data from nine exchanges in Mumbai, Delhi, Bengaluru and Pune.

Governments around the world are grappling with how to regulate cryptocurrency trading, and policymakers are expected to discuss the matter at a G20 summit in Argentina in March.

India has issued repeated warnings against digital currency investments, saying these were like "Ponzi schemes" that offer unusually high returns to early investors.

But it has not so far imposed curbs on an industry estimated to be adding 200,000 users in India every month.

The "V" shaped recovery in bitcoin (BTC) from Wednesday's low has stalled below the $12,000 mark in the last 12 hours. Prices on CoinDesk's Bitcoin Price Index (BPI) did rise to $12,045.09 at 15:14 UTC yesterday, before retreating to sub-$11,500 levels by 22:00 UTC.[1]

The slide from the high of $12,045 was extended further to $10,988.79 in Asian hours today. However, bitcoin soon regained poise and rose to an intraday high of $11,808.49 (at 08:44 UTC).[2]

The first bitcoin futures contract listed by Cboe has expired, a move that came amid a turbulent day of trading that saw the cryptocurrency's price drop below $10,000.

First listed in mid-December, the futures had a rocky start but ultimately those platform issues were resolved. The opening day for the contract saw the price climbing above $15,000.

According to data from CNBC, the F8 contract settled at a price of $11,055, a notable development considering that, at one point today, the price of bitcoin slid to as low as $9,199.59, according to CoinDesk's Bitcoin Price Index.

Yet in the period of time after the F8 contract settled, bitcoin's price appears to be reversing the trend it has seen in the past two days. At press time, the BPI is reporting a price of $11,344.66 – a figure that is just several dollars above the day's open.

Cboe data suggests that the market for its G8 contract (set to expire on 2/14) is trading slightly below the market, with the firm's official website reporting a price of $11,220.00.

As for what the future will bring for Cboe's work in the cryptocurrency space, a recent press event covered by Bloomberg suggests that the company may explore products built around other coins – but that is likely to come after more months of work around the futures product.

I'm a freelance tech writer, social media marketer for ICO's. Many of my clients offer to pay me in cryptocurrencies.
What are your thoughts? Is payment in cryptocurrencies better or shall I stick to payments in fiat currencies?

More than $200 billion has been wiped off the value of global cryptocurrencies at the peak of the recent sell-off, which extended into Wednesday morning.[1]

At around 7 a.m. London time on Tuesday, the total market capitalization or value of every digital coin stood at $653.8 billion, according to data from Coinmarketcap.com, a website that tracks the price of cryptocurrencies by taking into account the prices across different exchanges.[2]

This was when the sell-off began to take hold. As the price of major cryptocurrencies including bitcoin, ethereum and ripple fell sharply, that market cap declined by Tuesday evening to a low of $450.5 billion. The market cap, and the price of some coins recovered slightly from that low, but are still significantly lower.[3]

Bitcoin startup Blockstream has released a micropayment processing system that it claims makes it simpler to build bitcoin apps on top of its Lightning Network.

Called Lightning Charge, the system complements Blockstream’s existing Lightning Network implementation "c-lightning" and is intended to make life easier for developers creating Lightning-powered payments applications, the firm said.

According to a company blog post
""
Lightning Charge is written in node.js and its features can be accessed using an API via its JavaScript and PHP libraries, both of which are part of Blockstream's Elements Project.

"Web developers will ... get expanded functionality such as currency conversion, invoice metadata, streaming payment updates, and webhooks," the post states.
