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 ! Exactly, This kind of mindset is every crypto investors should have in their mind.
If you have regret invest in crypto, that means you cannot afford to lose what you invest.
Just think as an experience if you have done wrong actions. Cryptocurrency is very volatile, it will be normal if sometimes we make mistake.
