To the point of precious metals playing a role in investment with crytos, #1 it is smart to cash cryptos out in p. metals when the market is high #2 a lot of people are also selling metals to buy cryptos right now, so p. metals are currently a little easier & cheaper to acquire.
Personally I think BitcoinCash is a much better investment than BTC, however I feel EOS is now the best bet, if you know how to play your cards right with it. No one will sell EOS until June right before it releases, and you really shouldn't buy it until then either. EOS is currently at an all time high and recently climbed to rank #5 passing Litecoin on coinmarketcap.com.
