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.
You have made a great discovery about yourself, you know what you can do and what you cannot, many people thought that they could buy bitcoin and deal with its volatility only to find out too late that was not the case, at least you know that you are not willing to buy bitcoin for a cheap price because you know you will not be able to hold your coins if the price goes down.
