I look for differing uses, and I consider webot predictions.
For basic purchasing Litecoin has some history and growing interest.
For finance OMG is getting interest, especially in Asia.
EOS looks good for decentralized applications although ETH is first mover.
Bitcoin is still the safest bet. China may be adopting it. Hold long.
But think longterm. If you follow prices daily you'll find yourself buying high/selling low.
