There are a couple of considerations here:
1) Nothing is sure in life: With this I mean there is a possibility greater than 0 that you maybe wake up tomorrrow and for whatever surprising reason Bitcoin is now nearly worthless. What would be your personal situation now?
a) In case you have already 1 million USD in the bank and invested a couple of years ago 10 000 USD in Bitcoin, that would be a serious hit, but likely no changing your lifestytle dramatically, just a bad surprise.
b) In case you have 10 000 USD in the bank and currently holding Bitcoins worth 1 million USD currently, the loss would feel much harder and likley seriously impact your mental health.
c) In case you have 1000 USD in the bank and holding Bitcoins worth 1 million USD, the loss would likely give you suicidal thoughts.
2) Investing is all about making a profit over time. Depending where you fit in under 1 above, I would suggest in case you have already made a profit holding Bitcoins to consider selling an amount that you can then move to your bank account and is not affected by a total wipeout of Bitcoin,
Personally I would make a plan with certain tresholds lets say 100 000 USD for Bitcoin and when the treshold is reached maybe sell 30 % of your holding and HODL the other 70 % until the next treshold is reached. This should make sure that you survide a sudden wipeout of Bitcoin with at least a certain amount of profit and still have Bitcoins in case Bitcoins goes to 10 million USD or so.
Just my humble opinion
