Quite agree on above post; There has been too much good publicity about "Not putting all eggs in the same basket". Diversification can't mean to buy the 10 loudest noise projects (market cap) without even knowing what is all about.
In fact, if you scan internet you will find several projects in Medium blogs of people that put 1000 dollars on each of the top 10 coins in 2017, 2018, and so on. The few that are still posting results show you how lame it has been so far.
But of course past performance doesn't guarantee future performance...
