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.
We don't know really how much knowledge about crypto currency or Bitcoin of all participating on this forum, some are just new, etc.etc. One should note that Investment in crypto currency coin or ALT coin, must have a general knowledge about the possible coin investment he is planning to. on the above topic question, is it a simple principle of traders adopted " Buy low and Sell High". but on the long term investment, everything should be consider in the market (all information).
