Well I am also the one who was waiting for the bitcoin to drop down below 30k$ I want to buy some more for holding in a long term because I know that bitcoin will reach 100k$ in the right time.
If so, then is this the right time for you to make a purchase, or are you still waiting for price below $25K or $20K?
For whatever reason you should buy, then always consider using the amount of money you can afford to lose. We never know what will happen in the future because until now we only have 2 direction, up or down. You may really hope that the price of bitcoin will rise to $100K in the next 2 years after you buy it today, but sometime that hope will not come true when the fact don't match your expectation. There is always a possibility, at least you have to prepare yourself to get one of them.
