I am a proponent of Bitcoin Cash, but if something like this happens, even Bitcoin Cash could get absolutely whacked. I would probably tell you to hold some sort of more stable source of value and wait to pick up the pieces after this event. Even if something like this doesn't happen, I don't know how much more this Bitcoin bull can really run. It has no fundamentals left at all.
Look at Ethereum, Bitcoin Cash, Litecoin....Us dollars might be the safest of all. Buying things at all time highs rarely works out well.
Thats not true. It worked out well for everyone who bought Bitcoin at 1$, 10$, 100$ , 500$, 1000$ etc. All all time highs at some point.
