As much as I like the idea of STEEM it's just a little too new to spend a bunch of money investing in SP, maybe going into next year, but for now just buy a little to have more voting power. Gold, Silver and even Bitcoin has a longer track record from a logical investment point of view. I'm also with you on ETH, due to the Hard Fork i'm not sure what is going to happen so the risk is two high. Bitcoin is also having lots of problems lately and we don't know what will happen. Silver seems like the best way to go. It has been historically undervalued relative to Gold, if Gold makes a new high at say $3,000 silver should be at $200 in which case you will big in % terms. The problem is that Silver takes up way more space in your safe, so Bitcoin (all crypto) have a big advantage there on precious metals.
