How much is a Bubble a month?

I'm genuinely curious, could you please elaborate on this matter? I've heard people discussing the so-called 'Bubble' in the context of cryptocurrency investments, but I'm not quite sure what it refers to. Could you explain what a 'Bubble' actually means in this context? And more specifically, how much would it be, let's say, in a month? Is there a way to calculate or predict this? I'm trying to understand the potential risks and rewards involved in investing in cryptocurrencies, and this seems to be a crucial aspect to consider. Thank you for your time and assistance.
