I agree. I was recommended to buy NZD$100k worth in late 2017, which I did. Couldn't sleep at night worrying about it because it didn't make sense to me and I couldn't understand where the value was....unlike the yellow stuff.
After about a month I sold it all and made about $39k but I would be lying if I said I wasn't constantly worried about it. There is no ongoing yield or dividend on it, it is not money, nobody accepts it and it simply operates off the "greater fool" theory .... which qualifies it as a ponzi scheme. I was so relieved to be rid of it.
To emphasise the above, Wall Street have now got hold of it so it will be financialised like a FIAT currency and of course, don't forget ETF's will be built around the stuff - meaning you will never actually own the stuff. It will be a disaster!
