As Blythe Masters said :
You should be taking this technology as seriously as you should have been taking the development of the Internet in the early 1990s. 
So just put money every months in bitcoin and others altcoins , just a bit , but with the time , it will be a snowball !
But remember ,
WHEN YOU INVEST , JUST THINK THAT THE MONEY IS LOST ! and invest what you can loose ! Here my best Cryptocurrency Portfolio :

- 30% BTC
- 20% ETH
- 15% NEO
- 15% ADA
- 15% FSN
- 5% ICOS
Of course, I dont have regrets in investing to my assets like Bitcoin. It was designed for the long-run, as it was meant to be a difference maker in todays generation. Its a good thing you have that kind of portfolio, and just believe that it will be worth it in the long run.
