Not sure that I believe in the Lindy effect per se as if tomorrow there was a digital currency that was better than BTC it would ultimately disrupt and displace BTC. The observation of a Lindy effect is down to the qualities and specification of BTC and the network effect that results . Despite the technical issues surrounding BTC which still need to be resolved IMHO it was carefully conceived and specified as a "utopian" digital currency / store of value . IMHO the same cannot be said of many of the BTC's alt-coins competitors that are technically inferior with respect to BTC & seem to be just vehicles for short term financial gain via speculation.
