bitcoin today has gone up 6%, the proof is that it has improved from before with the price having reached another $31k before it fell below $30k.
so op's predictions don't seem to match the real conditions on the chart
OP said above $30K for 10 consecutive days. That means it could rise to that level but it would not be able to maintain it for the next 10 days (it could go $29K again). I've watched some TAs that price could go to $27K by the end of the month.
and it looks like bitcoin already has support for big investors.
A lot of people have been saying that since it reached $60K but it's still declining.
