You should take a look at the 3rd generation blockchains like Aion that connects multiple blockchains together forming ecosystem (like a blockchain internet)
For sure put a part in Bitcoin and Ethereum. I would also consider 3rd generation blockchains such as Aion and Cardano. Another one that recently completed ICO is Wanchain, I think it will be big as well.
Sell your bags of Bitcoins and altcoins. I'll be happy to buy them at a discount If you don't see the true potential of blockchain technology it's your loss, there are soo many problems outside of financial transactions that blockchain can solve.
