FUD can really work for these manipulations. But there have been FUDs in the past that never had work and that's why when there are FUDs like this, they're becoming more extreme than in the past.
I expect that there's more to these FUDs and they're going to be more brutal and fearing when they come but remember, that all you have to think about is the long term and accumulate when they exists at the moment for you to take advantage of it.
It is also important to try to take the smallest risk possible, the people that are getting liquidated due to the current crash are people that were using a massive amount of leverage on their trades, however those that were invested in bitcoin without using any leverage have only lost 20%, an amount which they can easily recover if they hold for a few months or if they perform a DCA strategy, obviously it is too late to do anything for those that were using leverage but it is a good idea they keep this in mind as I think this will happen again.
Small risks can be done buy buying smaller quantities but this can stack up if we decided to invest for long term so the risk also grows. People shouldn't panic and start liquidating their assets during this situation that we are experiencing now. Doing so will only make them lose but if only they will calm down and continue to hodl, then there will always be a chance that their assets can recover once this storm passes by.
It might be too late for those who do leverage but they can always start again now that prices are still cheap but this time, they shouldn't do leverage as it was too risky and events like we have now can happen unexpectedly.
