Good point.
A cursory search on investment tips from viable sources had been suggesting, all along, that a 1% portfolio exposure is ideal for crypto (that 1% includes all miscellaneous e.g. ponzi IPO, fake ICO, alt and actual crypto cash, bitcoin, bitcoin cash et al). Heeding that suggestion, since I had $400 in my bank account, I invested $4 on cryptos. It will not make me rich. Tulip bulb mania or not, once the payment transaction logs are securely separated from underlying transaction ledger thereby reducing the byte size per transaction, whatever that alternate secured currency is, will be the king. But like Ronald Wayne, I don't know at this time.
