Of course you can be rich with Bitcoin and still have the right time to buy Bitcoin. Because Bitcoin's price is very low and now it is possible to earn a lot of profits in the future. So, I do not think you'll miss this golden opportunity.
Do you think that bitcoin will still rise again its price in the future? If that's so, then it is really better to buy bitcoins now, as long as bitcoin as its low price today. Just like when bitcoin last year, most people buy bitcoin at $7k then wait until December so they get profited last year, but to those who buy bitcoin at a high price lose their bitcoin because it drops hard also. 
We all really don't know when the market will recover or will drop again.
