Steem is the best crypto you can aim for in my opinion, it is just dominant.
Most usable blockchain globally, while using 0.3% of its capabilities. Pretty crazy right?
And it is actually a functioning blockchain - getting developed day by day
SMT's and whole 2018, could easily go to 100$
But, on the other side - Litecoin should be listed as a payment option on Amazon. Could easily moon 5k... You never know man.
But if you are passionate about steem, use it regularly - doubt no more. Put most of your assets here. Make sure to hodl a bit of NEO and LTC to make sure you diversify :P
