To me I think every time is the right and best time to buy BTC so we should go on and buy any amount we want to and stop all those post because when you buy now there will surely be a time to come where it will increase in price for you to enjoy it. We can buy and sell anytime and anytime is the best time. What do you think guys? Any suggestions?
Are you really buying bitcoin or you are just suggesting others 
I don't think its always good to buy and sell bitcoin because if you will buy at peak price than how you gonna recover it when you actually need some cash?
Many have lost all of their savings on bitcoin when they bought huge amount of bitcoin during 2017 boom and right now struggling to pay the debt because some of them have even took loans to invest.
My suggestion is Sell on peak and buy at dump is simple rule of trading, just follow it.
One should note that, Market is Volatile, for a traders, every time is good time for investment, the stay in the market, monitoring every ups and down during the market trading as posted. if look back and take a look on the market history of Bitcoin, some are able to gain more profits when the price value of Bitcoin Spike high to the roof, then dump them on the down stream of the market. Patient is the KEY and the TIMING to invest. learn more the market.
