1BTC currently = $384 which is an absolute bargain.
I have sincere doubts that the price will dip below $300. The price isn't dipping naturally, if you look at the charts - that stream of red candlesticks would suggest that there was some sort of catastrophic news released on every media platform in the country about bitcoin - that obviously isn't the case.. so the price is clearly being manipulated downwards.
The only reason you'd want lower prices is to buy in cheap, in order to realise exponential gains when the market corrects.
This happens every day in the altcoin markets but on a smaller scale.
In altcoin land, this would be referred to as the "accumulation" period - during which manipulators are able to control the price by creating artificial sell resistance to stop prices rising, and also putting in some buy support to prevent the market going into free fall. This allows them to 'accumulate' coins within a specific price range before removing the sell resistance - allowing the correction to occur.
Is bitcoin a buy right now? absolutely positively yes!!
Historical evidence shows that every year between Oct - Dec bitcoin surpasses it's previous all time high. So, if you buy in now - the price only has to jump to $700USD for you to have doubled your money... and I am quite sure that btc will have no problem blowing past $700.
Just look at coinmarketcap.com... every time the price of btc dips, the trading volume goes through the roof. Just today there has been $32Million worth of trades.
