I think it's a good start though I just have 3 points for your consideration:
1. don't invest ALL your savings, save some for a rainy day. Maybe start with $5000 instead.
2. consider allocating higher % to bitcoin (60-80%)
3. consider allocating into 1 or 2 more altcoins in different verticals (e.g. anonymous coins such as xmr or zec)

i've been lurking for a long time (couple years), and imo the best strategy is to dollar-cost-average into bitcoin from the first day you decide to invest. it's not easy to know when the floor is, so if you plan to hold BTC over the long term (3-5 years), your best bet would be to start by buying every week or every month for the next year or two.
