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.
Yes, it is always a right time to invest in Bitcoin, for the traders any market movement is an opportunity to trade in the market. and for investors it best time to invest when the market is down, you can buy coins at low price and just wait until the market recover itself after the market drop. Bitcoin remain number one among all ALT coin in the market as posted, with good fundamentals, clear market structure. I am optimistic that Bitcoin will make another possible bull run anytime soon.
