I beg to disagree on that Everytime is right to buy and sell. You will only end buying too high and selling to low and at such put yourself in great loss. Better learn the rudiments before driving into any trade.
I think what the OP is trying to imply is there's no wrong timing when it comes to buying bitcoin because it will surely make you profit because it is stable now and constantly rising but what bitcoin as it is now, it is seems wrong because currently it become very volatile. if you believe what the OP says you will surely lose money because there's always a right time when buying btc and it is when in down trend.
