My strategy: Buy a set amount every month (a set amount of fiat, the btc I can buy goes down every month!)
I am buying to hold long term. I also may diversify into alt-coins or ICOs in the future, but keep the bulk in btc.
I have a quantity of ETH which I'm holding long term
I continue to accumulate Steem & aim to buy & hold
(you can see I'm not a trader!)
Strategy 2017-2018: accumulate btc every month.
