I think you did a great decision buying those altcoins because there are already in the top 100 and their project is in active development and their community support is great especially eos. Well we are still in a bear market but hopefully before 2019 ends we might see a bullrun.
I think buying altcoin in the top 100 coins in coinmarket is still too risky, we should buy in the top 10 coins on coinmarket will be safer and it will help us to be less worried.
I also think that way, because with the altcoins that are in the best positions, they offer a certain degree of security, however, the moment I begin to speculate with the altcoins, I only study the first 5 coins of coinmarketcap, this because always I like to have some kind of position with the alts, always very aware of any movement of the Bitcoin, to have a quick reaction with the altcoins.
And there is something very important, that at the time of studying the altcoins their graphs are similar to the bitcoin graph, since they have a structure and history, they are not nascent currencies, in which you can not have a clear vision where you can go.
