Definitely thinking using blockchain as a platform is going to be huge. Matter of fact, that will be were most of the adoption comes from. Digital currency in itself will be smaller.
Blockchain tech for Supply Chain and for Shipping will be huge.
I have invested in: Trac (Origin Trail), EVE (Devery), VET (Vechain Thor), WTC (WaltonChain), CARGOX (CX0), and ARY (Block Array)
I believe all of those will go at least 10x, however the smaller cap like EVE, TRAC, ARY, AND CX0 will possibly be 1000x's by end of year.
