If one truly believes in the longevity and robustness of crypto currency, then my 2 cents is invest for the long term in a coin/token you like based on its application, team behind it, its community, and also something that interests you i.e. if you like blogging consider steemit.com, if you are a musician consider muse etc. start to buy bits at a time, grabbing some on the dips, wait and hold for any blow outs and take some off the table as they go up. Spread your investments to a few coins and most importantly never invest anything your not prepared to lose. If you don't know how to trade at all just walk away and come back in a few years and you should have a tidy profit :)
