Stephen is well worth following on Twitter and Steemit. As a follower, I have to say, he is a fan of gold and silver too but it is so easily manipulated with worthless paper gold and silver on Comex. Still I would agree with a diversified portfolio. But Crypto is part of that diversity. I hold silver, gold, lithium and tantalum miners, #LTC, #BTC. I'm also bullish on copper. I'm new to crypto but I'm a convert already.
