Me either. I never predicted anything related to its success or demise but I work in finance and have a masters in business administration and I have never been able to adequately explain to myself exactly what the relative advantages Bitcoin or any e-coins are to fiat currency, while having a pretty immediate understanding of the potential risks.
In this case, it seems that an e-exchange in an unregulated market provided a means to an end for a charlatan to loot his customers. But crypto was a convenient path. I'm not sure it's now definably wholesale worthless because of FTX, though it may prove so eventually.
