More drop in price then its better discount deals 
Just aim for what is coming after the drop because before price went to 65K from mid 3K so now even if its 2 digit and minimum of 10x just 50% from the previous ATH can get the figures into 5, so buy at 20K and waiting for 100K in just a year or two doesn't seems to be a stupid idea.
Based on charts and history, the current heavy discount on bitcoin "70%" is a great price to buy and hold in the long term. It's hard to say no when an opportunity like this arises and lasts for a few months, for me this is the best opportunity to buy but of course by combining several strategies like DCA and accumulation.Just aim for what is coming after the drop because before price went to 65K from mid 3K so now even if its 2 digit and minimum of 10x just 50% from the previous ATH can get the figures into 5, so buy at 20K and waiting for 100K in just a year or two doesn't seems to be a stupid idea.
I think it's safe to assume that this is a good time to buy as much bitcoin as you can afford, but certainly for an amount you can afford to lose. But none of us dare to guarantee the future because actually bitcoin is always difficult to predict.
