"As the decline of the US Dollar continues, Bitcoin (BTC or BCH or BTG) will rally (as they have already been doing).
Once people realize there is no limit to the amount of competing cryptocurrencies (altcoins) can be created, they will realize that most cryptocurrencies (with the exception of "OneGram", backed by physical gold in a vault, or concepts like ETH or EOS where they are not currencies but foundations of a useful new platform) are virtually equivolant to a FIAT currency with no checks and ballances they will move to the TRADITIONAL stores of value,,,, aka GOLD and SILVER." <---- You are ahead of the curve there, yes, in a few years Gold and Silver are likely to go up quite a bit. I think digital currencies are with us to stay, but whatever happens with price, they are teaching people about money and value. Many will diversify into Gold and Silver to be safe from fiat.
