In the currency circle, don't worry, wait patiently for the market. This is a key element of investment. When you invest in Bitcoin, if the price of Bitcoin drops, you can choose to hold Bitcoin for a long time. Don't do things that you regret because of these panics, causing the loss of a lot of assets, don't give up, it will bring you considerable gains in the future.
If that being said for OP to wait and for sure it takes longer as we expected and I'm afraid if he misses the chance to but at a cheap price since the market is already making a continuous rally. If he is able to manage it before this current surge, that probably he is happy now but unfortunately, it was done already and he needs to wait months or even a year. Or, he will take a risk more by buying the current price at $50k. Because if he ever believes that the next ATH is above $60k, that still it gives him some ROI.
