Jay has already explained it -- 6 digits = $100k+/coin. Assuming a 20 BTC stash, this is entry-level spot price f.u. status (whatever the implications of spot price vs. 200 WMA may be). You seem to be describing a situation where a mere couple of coins can achieve this, so then, yes, a 7-digit spot price would be needed.

In any case, I quite like the $2M as the entry-level f.u. status threshold, but I tend to multiply it by about 5, in order to secure it against unforeseeable events that may affect spot price. Basically this is very roughly equivalent to using the 200 WMA (my beloved indicator) as a basis for any calculations/predictions when it comes to spot price mega-pumps that are not likely to affect the 200 WMA value much in the short term. IOW, the 200 WMA acts as a filter, shaving off any spikes (up or down), effectively setting a (quite reliable IMHO) lower bound envelope for spot price (although that envelope has been broken a few times, esp. during the mid-2022 to mid-2023 bear period).

How big must the upcoming pump be, in order for the 200 WMA to reach $100k? Looking at past cases of spot vs. 200 WMA prices during pumps, it seems that the spot/WMA ratio tends to go down with time.

End of 2013: 28x
End of 2017: 16x
End of 2021: 4x
End of 2025: ???x

For the purpose of this exercise, let's SOMA-guess that it's going to be around 3x. This would mean that the spot price at the end of 2025 would be around $300k. So, 20 BTC would be right at the entry-level f.u. status threshold (according to the 200 WMA of $100k), with the added cushion of 3x f.u. status of $6M (based on spot price).

Looking forward to filling the green part of my post...
