It could all be worthless one day, but play the odds. Bitcoin could just as easily be over $100k plus with the next year or so. Would you buy something, or a proportion of it, for $35k that had just as much chance of going to a $100k as it does to $0.01?
There is another poster who made the comparison to tulip mania in this thread back in May 2020.
If that same poster had purchased BitCoin in May 2020 they’d have more than trebled their money.
It my opinion Bitcoin still has way more upside than downside at $35k or whatever it’s at at the moment.
