When it comes to advantages, BTC has "first", "biggest", and "most well known". Other than those, which are huge, no doubt, I fear it will not be the winner in the long run. I'm investing in BTC, ETH, and LTC because those are all GDAX had when I started a few months ago. I'm looking for an exchange where I can get into IOTA but not liking the buzz around the ones that currently offer it. Because I'm not a deep thinker my main chance in this game will be diversification.
