Right now, it's the best time. When the value of Bitcoin is falling or low, we can rely on that opportunity to buy as much, and when Bitcoin has gone up, it's the right time if we want to sell it. Through this,you will really have a great profit after holding them from a long-term investment.
In my opinion, more time someone spends on deciding whether to buy bitcoin or not at any moment, more expensive it becomes to grab this volatile digital currency. During the last dip when everyone was selling out and leaving side of bitcoin, I kept on spreading words like "this is the right time to buy bitcoin" but looks like in was ignored. For me, it is a bit late to buy BTC but still, this is the last chance.
