please its there any place i can get cheap btc and start selling and buying everyday.i will purchase at least 1000$ a day
There are no more cheap bitcoin today and the cheapest bitcoin available is priced at 1000$ +. But if you want to get a good price try using cryptocompare in google, this site allows you to check all the bitcoin markets including their price. By comparing all markets you can determine whom among the markets are selling bitcoin at a lower price.
Maybe he meant volume, not valuation. I would point at the bigger sites like Bitfinex, Bitstamp or Kraken just flip throught the list at
https://coinmarketcap.com/exchanges/volume/24-hour/ and pick number 1, 2 or 3.
Unless you need to enter the market with renminbi but you said $ so I assume these allready are your shortlist.
All personal or local exchange doesn't fix the lowest price, they refer to trading price, so if you are looking for best price, please visit some respective trade market are available. Yes, coinmarketcap is best place to find references market and right prices. BTC 1000 usd = 0.87 is average price at the moment.
How this bitcoin works?
can anyone use it in any transaction?
Just like Fiat, Bitcoin is a virtual currency that everyone can use and has been widely decentralized.
