There is a rumour going on about an potential $500 billion investment into BTC by the Saudi governments
Rumor is rumor and you should not trust rumor and action because of rumor.
Focus on history like historic cycles, halving effects, length of bull and bear markets then make your investment plan to enter and exit the market.
HODL your bitcoins is key to get profit and avoid panic, fear and lose your bitcoin by selling because of news, rumor.
Buy rumors, sell news and that's the way many people use it to make a lot of profit. We don't need to be afraid of rumors, but we need to verify them before deciding whether to believe them or not. Just as many people made huge profits from ETFs rumors for months before it became a reality.
The historical cycle can also change or not repeat, we can expect history to repeat but don't be too subjective because nothing is 100% certain. There is no evidence that history will definitely repeat itself, everything is just predictions and expectations.
