Definitely yes you can still rich to bitcoin once you invested to the bitcoin right now because price is cheaper but if you want to wait to dump more is okay but time is gold and you need to grab this opportunity and for sure the result is good and satisfy.
I like your opinion, but if I adopt your opinion, this is a big challenge for me if I buy bitcoin when the price drops dramatically because what I'm afraid of is if bitcoin falls even worse than the current price.
In this fear people have lost million of dollars to earn because whenever their is a drop everyone feels it will drop more and more. Generally after drop btc rises far more better than to what level it has drop. Only this year it has being other way so one who needs to earn will be buying on dips.
