For a wildcard pick I would say DigiPulse.  June/July specifically with the platform launch slated for July.  Just recently burned over 50% of total supply and has a very low circulating supply 2.2m trading currently at 1.51 USD which I believe is extremely cheap and could see a nice pump as the platform gets closer to being launched. Price could also increase throughout 2018 as its one of a few who are going after the digital asset inheritance space.

If you do some basic due diligence you will see other competitors have limitations or involve third parties (lawyers) which blockchain should be cutting out the middle man and not including them.
