I disagree for two reasons: 1. I’ve become convinced that the crypto currencies with applications (ether, xrp, and others) are actually riskier than the simple store of value coins like BTC. If, for example, dapps don’t really take off in popularity and the “application” of the crypto currency fails, I would expect that would tank the value of that currency. BTC or LTC, which seem more like simple store of value coins at this point, would appear to have less of this type of associated risk. 2. Ripple (XRP) in particular seems doomed to me. I do not believe that any major financial institution would use a public blockchain and associated currency. If they need / want to use blockchain, there are non-public options that would better serve banks, some being developed by the hyperledger group and others.
