I got a some project like yours, but my plan is to achieve 0.5 btc before june 2018, 1 btc at the end of year.
So this is my road map or basket you can say,
Invest some solid altcoin. Not ethereum(which can be an option too of course) like neo. - %50
Invest some potential coins like icon(icx) - %30
Invest some speculative coins (for now) like ripple, cardano, xtrabytes. - %20
I have found that diversifying my portfolio in multiple altcoins has proven to be the most stable growth in 2017. Yes you can go all in in one coin and hope for the best, but is not often the best method. Three coins are decent but can be a bit frustrating as there are so many good projects on the market and if you're not in the pump it can seem like ages before it is your turn. When you have for instance 5 or 7 coins which have a good product it is much easier to get a stable pump every week. Especially 2018 will be the year for altcoins so it is always worth the effort to search for new project. That x10 pump could be only a matter of weeks if you invest right.
What is your starting capital if I may ask? Just out of curiosity.
Anyways, good luck with your investment.
