I want to do something similar to you, however I count with less capital, should I raise my capital or invest my $ 200 in one promising coin then diversify?
When playing with $200, I would suggest you invest in fewer coins. Apart from this $100 each project, I do still trade much more into other coins on more frequent phases. With this $100 a coin project, i'm just going to be HODLing the whole time no matter what and see where it takes me till 2018. But I would suggest you climbing up that ladder, putting into 1-2 coins, take profits and putting into new coins (repeat). If you have enough already invested and have $200 more to just chuck around, then sure!
That's just my opinion
