Great analysis and I like your prediction. The first two threats cannot be ignored. You can be sure that Vitalik is already working on the sharding technology and ethereum already has a big following. I'm sure he has a personal mission not to let EOS eat his lunch. After all, EOS has been dubbed "The Ethereum Killer" as well as "Ethereum on Steroids" for its abbreviation.

As far as the cryptocurrency market crashing and not recovering for a long time (just like when bitcoin crashed in 2014 and just stayed down for 2-3 years before finally started its upward trajectory again late last year) is always a possibility to consider. This is always on the back of my mind otherwise I would have already gone all-in (and I mean bet-the-house-all-in-into- cryptocurrency) and that's why I haven't.

The risk/reward ratio is indeed extremely high. If you get to your 100K EOS holdings goal before it reaches $20, you'd have $2 million by the time it reaches $20. The next step, reaching the top 3 market cap in 2019, well, let's just say that you won't need your 401K money by then!

Excellent post. Keep up the great work!
