I concur. At current prices, you cannot ignore Bitcoin as a serious investment for the future. Over the past months, it has stayed below its All-time-high of $20,000 per coin last year, so it would be wise to stack up your fortune now before it's too late. Because you can rest assured, that once prices start to rise at unprecedented levels, there would be FOMO among new people in crypto land, leading us to a bullish market for quite some time.
As such, you can buy Bitcoin right now, to earn a lot of money once it gets past the goal of $20k per coin. Once this happens, you can either cash out into fiat, or simply convert your Bitcoin into a stable cryptocurrency like Tether, Dai, or BitUSD which protects you from the massive inflation inherent within the original cryptocurrency (BTC). If you do this, no matter if Bitcoin's prices decline massively, you'll have the same valuation in fiat, allowing you to purchase even more coins at cheaper prices than before, for even greater profit in the future. Repeat this, and you might become successful with your Bitcoin investments.
All in all, I think that every time is the perfect time to buy Bitcoin again, since it doesn't have a standard value attached to it. The cryptocurrency could either go crazy in price going to the moon, or all the contrary. It's up to you to choose the perfect moment to execute your investment strategy.
